What to do in case of mining disaster

1. In my world instry 2 experimental version, electrical appliances will not explode e to high voltage
low voltage transformer can be made in instry 2 advanced solar mod:
Advanced Solar helmet:
medium voltage transformer can be made in instry 2 advanced solar mod:

Tesla coil, high voltage upgrade and high voltage transformer
high voltage transformer can be made in instry 2 mod:

replicator, hybrid solar helmet, ultimate solar helmet, super high voltage transformer (instry 2 advanced solar energy)<
ultra high voltage transformer can be made in instrial 2 advanced solar mod:
molecular recombiner:
introction of instrial 2 original transformer:
transformers can be divided into high, medium and low, but the principle is basically the same. The surface of one dot on the transformer is a low voltage node for input and output low voltage, and the surface of three dots is a high voltage node for input and output high voltage. High voltage to low voltage wiring method: connect the high-voltage electricity to the surface of three points, then the low-voltage electricity will be output from the surface of one point. Low voltage to high voltage wiring method: connect the low-voltage electricity to the surface of one point, connect the activated red stone wire to the transformer (or directly install the switch to the transformer), then the high-voltage electricity will be output from the surface of three points. PS: the high voltage and low voltage mentioned above are relative. For example, 128eu / S is high voltage electricity relative to 32eu / s, but it is low voltage electricity relative to 512eu / s
note: the direction of high voltage node can be adjusted by wrench.

2. In order to save themselves and each other scientifically, we should also implement the "six risk avoidance systems"

"relying on the three-level underground protection system, through scientific self-help, we can greatly rece the occurrence of casualty accidents." Li Qingfeng, vice president of mining Engineering Research Institute of Hunan University of science and technology, said

the so-called "self rescue" refers to the method of avoiding disaster and protecting themselves in the disaster area or affected area when an unexpected disaster occurs underground. However, Li Qingfeng stressed that in addition to self-help, people in the accident also need to master the method of rescuing injured companions on the premise of ensuring their own safety, namely "mutual rescue"“ Before entering a new operation site, miners must learn the operation proceres and safety technical measures of the operation site, and be familiar with the ventilation system condition and disaster avoidance route of the operation area. Of course, it also includes mastering the disaster prevention and emergency plan of the mine, skillfully using self rescuers, and mastering the omen, nature, characteristics and disaster avoidance methods of various disasters and accidents. Mutual rescue includes basic methods for rescuing the injured in the disaster area and learning the most basic first aid operation techniques on the spot. "

"in addition to the miners' knowledge of scientific self-help and correct operation, advanced and reliable underground protection system is also needed for successful rescue after disaster." Hao Xiaoli said

"the notice of the State Council on Further Strengthening the work of enterprise safety in proction" and "the notice on improving the" six systems "of underground safety and risk avoidance" clearly put forward the construction of underground safety and risk avoidance systems in China's coal mines, such as monitoring and monitoring, personnel positioning, emergency risk avoidance, pressure wind self rescue, water supply rescue, communication and liaison, so as to comprehensively improve the safety guarantee ability of coal mines

"the construction of" six risk avoidance systems "plays an important role in protecting the life safety of trapped miners after the accident and improving the success rate of rescue. However, e to multiple factors such as technology and economy, this measure has not been well implemented. In order to ensure the safety of miners, it is suggested that the government and enterprises should work hard to implement this measure to truly realize the safe and efficient proction of coal mines. "

3. Ah. This problem is too worrying. In fact, the real mine disaster is in a confused state, like a dream

4. The following is an article I wrote in 2005, hoping to be helpful to your questions<

discussion on gas explosion

it was only two and a half months since the extraordinary gas explosion accident occurred in Chenjiashan coal mine of Tongchuan Mining Bureau in Shaanxi Province on November 28 last year, 166 people were killed, and the earth earthquake in Sunjiawan coal mine area of Fuxin occurred again, with 212 miners killed, It has become the biggest mine disaster in China's coal instry since 1960 (the biggest mine disaster before was the gas and coal st explosion in longshanmiao coal mine of Pingdingshan 44 years ago on November 28, 1960, which killed 187 miners). After 24 hours, a gas explosion occurred in an illegal small coal mine in Songlin village, Zhuyuan Town, Fuyuan County, Yunnan Province. So far, 27 people have been killed and 14 injured. Not to mention that the frequent occurrence of mine accidents in China is related to extensive economic development mode, weak awareness of enterprise safety proction (such as focusing on proction and neglecting safety), low technical quality of some managers and operators (illegal operation, unable to find and eliminate hidden dangers in time, poor ability to deal with emergencies, etc.), some responsible persons in mining areas are driven by economic profits, and collusion between officials and businessmen in indivial places, I just introce the explanation of terms related to gas explosion and how to prevent gas explosion in coal mines, which is a reference for the proction department of our company to do a good job in safety work
Coal: ancient plants were metamorphosed by underground high temperature and high pressure under the condition of lack of air or air
coalfield - a large area of mineable coal seam distribution zone
gas refers to all kinds of combustible gases (such as gas, biogas, etc.)
gas generally refers to the gas obtained from the dry distillation of coal, which is mainly composed of hydrogen, methane, ethylene and carbon monoxide. It is used as fuel or chemical raw materials, but improper use will lead to gas poisoning or explosion
gas poisoning is commonly known as carbon monoxide (CO) poisoning
the three elements of chemical combustion and explosion are combustibles, combustion aids and ignition sources
carbon monoxide is a colorless gas with the molecular formula of Co. it is a toxic gas and is easy to explode when burned with oxygen
carbon monoxide poisoning refers to the combination of carbon monoxide (poisonous gas) inhaled by animals and hemoglobin in the blood, resulting in hypoxia poisoning in animals, which can be fatal in severe cases The poisoning of Sunjiawan coal mine in Fuxin is caused by carbon monoxide
explosion -- the phenomenon that the substance changes, increases rapidly and releases a large amount of energy in a very short time, which is mainly caused by chemical reaction or nuclear reaction
explosion limit refers to the concentration range in which a combustible gas or mixture of vapor and air can explode. When the air contains combustible gas (such as hydrogen, carbon monoxide, methane, etc.) or combustible vapor (such as ethanol vapor, benzene vapor, ethyl acetate vapor, cyclohexanone vapor, tetrahydrofuran vapor), within a certain concentration range, Sparks will spread the flame and explode. The gas explosion limit of coal mine is 5% - 16%
gas explosion gas explosion in coal mine refers to the concentration of combustible gas (composed of hydrogen, methane, ethylene and carbon monoxide, etc.) in the mine air. Within the explosion limit, the flame will spread and explode when encountering sparks, which is destructive and lethal
in my opinion, the most effective way to prevent gas explosion and poisoning in coal mine is exhaust ventilation, so that the gas content in the mine air is lower than the lower limit of explosion limit, and the CO content is much lower than the maximum allowable concentration. In addition, the ignition source should be eliminated in the mine, and the original stable geological structure should not be changed ring coal mining, so as to avoid mine tremor. It is also necessary to protect the gas monitoring system and check and maintain it in time

5. Mine disasters mainly include: gas explosion, water penetration, roof accident, pyrotechnics explosion, carbon monoxide poisoning, carbon dioxide suffocation, mechanical and electrical accidents, etc. In fact, these can be said to have strict safety regulations. As long as they are observed, accidents can be basically avoided. Many accidents have omens. For example, the omen before water penetration is that there is water seepage in the working face, the air becomes moist, the temperature decreases, and there is slag falling from the roof or side wall. Gas explosion is mainly caused by the gas concentration in the air to a certain extent, which will explode when there is spark or even static electricity. Carbon monoxide, carbon dioxide and other gases are proced ring the explosion. We all know that carbon monoxide is a highly toxic gas, People will die within seconds of touching it. The main purpose of the roof is to knock on the top, that is, to listen, to see and to knock on the top. I once met with carbon dioxide and fainted on the spot. Fortunately, I didn't die. I also saw the worker die in a roof accident. Rescue to see what the accident, such as gas explosion, the first is to ensure smooth ventilation, usually use oxygen cylinders, poison detector, etc

6. The correct self-protection posture is to look for the edge of the mine, or the intersection of the mine, squat down by the mine, hold your head with both hands, protect the main parts of your body, at the same time, don't panic, keep calm and wait for rescue

7. One of the reasons for the integration of small and medium-sized private coal mines in Shanxi is that the safety proction of such private mines is not in place and accidents occur frequently. Just at this time, the "11.21" gas explosion accident occurred in Xinxing Coal Mine of Heilongjiang Province, a large state-owned mine. 108 people were known dead and 65 were injured in the hospital. The accident happened in the former state-owned key coal mine of Hegang branch of Heilongjiang Longmei mining group, which was once one of China's top 500 enterprises and China's top 100 coal enterprises. Four years ago, more than 170 people died in the gas accident in Dongfeng Coal Mine of Qitaihe branch of Longmei group. I sigh that such coal and electricity are bloody
with the continuous coal mine disasters, China has become the country with the most coal mine disasters in the world today. The death rate per million tons of coal in China was 2.041 (previously 2.83). India and South Africa, which are also big coal developing countries, have a mortality rate of 0.5 per million tons, which is 1 / 4 of ours; In the United States and Australia, there are 0.03-0.05 people, which is 1 / 40 and 1 / 50 of ours (according to Li Yizhong, former director of the State Administration of work safety in 2007). In addition, the pollution caused by coal mining, transportation, combustion and power generation - all kinds of waste water from coal mines account for 25% of the total waste water in China; There are more than 6000 coal storage yards in China, most of which are open-air and lack of st prevention and control equipment. About 10 million tons of coal st are proced every year, and 11 million tons of coal st are proced in transportation; Coal combustion is the largest source of air pollution in China, accounting for 70% of the national soot emissions, 85% of the sulfur dioxide emissions, and 67% of the nitrogen oxides emissions....

today, coal is mainly used for power generation. Under the energy source planning idea of "coal as the main body (accounting for 70%) and" power as the center ", power has become the constraint and pressure of development economic growth, Coal has become a hindrance and pressure for the development of electric power, and the superficial "want to develop", lack of coal and electricity, has covered up the interests of some places and enterprises regardless of human life

at the same time, China's energy consumption per unit of GDP is 8.33, the world average is 2.65, and that of high-income countries is 1.66 (all 2004 figures, 2008 International Statistical Yearbook, National Bureau of Statistics). That is to say, in China, to create the same output value requires several times more energy than the world average - a considerable part of which ultimately comes from coal

the State Council has set up a special accident investigation team headed by the director of the General Administration of work safety. The relevant authorities immediately formed 108 working groups with three people in each group (one female comrade) to go to the homes of the miners who were killed or whose whereabouts were unknown for "Consolation" and to send each family 100 Jin of rice, 20 jin of dried noodles, 20 jin of eggs and 20 jin of soybean oil. The compensation will be paid as soon as possible. But why can't there be effective system improvement and fundamental change for the safety proction problems related to workers' lives<

it seems different from previous times. On the second day of the Xinxing Coal mine accident, the all China Federation of trade unions, Provincial Federation of trade unions and Municipal Federation of trade unions sent 1.6 million yuan to the families of the workers who died. However, it seems that what the trade union should do more is to claim rights for the workers. At ordinary times, it shouts loudly for the safety of the miners. After the mine accident, it comes forward to complain injustice for the dead miners, and it comes forward to file civil lawsuits on behalf of the dead miners to claim compensation (on the premise that the procuratorate initiates public prosecution on criminal cases)

in the face of repeated mine disasters, what our society should do seems to be lacking, which is the construction and improvement of the system. Life and health are the basic rights of workers. The life and health of workers should not only be the protected object. In proction safety, in society and even in the political life of the country, workers themselves, as human beings, should be the subject whose rights are recognized and respected; If their rights are violated, there should be systematic legal relief. As the ruling party, the central document of the Communist Party of China once proposed that our society should construct four mechanisms in the transformation, namely, the protection of rights and interests, the expression of demands, the coordination of interests, and the mediation of contradictions. It is in this case that we will find that in the face of mine disaster, the trade union not only lacks the expression of anger (not anger), but also often aphasia; Miners are less involved in the daily safety proction, in the company's decision-making of underground proction operations involving safety, in the reliability, maintenance and replacement of safety proction facilities, and in the protection of rights and interests related to life and health. In the past, it seemed that it was only the business managers and government regulators who needed a system to ensure that the voice of workers' demands could be conveyed and that workers' actions could play a role in the critical moment of their lives

How can we fundamentally solve the problem? First, in the value concept of "people-oriented", in the proction of human life in the first place above all. In the past, in the age of revolution, there were always sacrifices when it was said to struggle. Today, in the age of attaching importance to human development and pursuing harmony, it is unacceptable that people die in proction because of accidents. Second, when our society has been formed in which the interests of different groups are different, we need to balance the interests - the coexistence of market economy, the rule of law and the balance of interests, which is a good society. Here, trade unions must play a role. Third, development needs energy, but is it necessary to use coal? Must it be picked, transported and used in this way? Coal will run out sooner or later. Whoever takes the lead in new energy may lead the world. The 17th National Congress of the Communist Party of China not only reiterated the basic national policy of "persisting in resource conservation and environmental protection", put forward "improving the efficiency of energy and resources utilization", but also put forward "developing clean energy and renewable energy" and "actively carrying out mutually beneficial cooperation in international energy and resources", which may be good ways to avoid mining disasters.

1. The relevant responsible persons should be held accountable seriously. You Xiaobin, chairman of Lvxin coal company, Yao Guoqing, mine director, Yin Yongliang, deputy safety director, Hao Jinwu, deputy proction director and Zhao Zhenjing, chief engineer, were dismissed. Feng Letian, deputy head of Heshun County, Zhang Ruitao, director of coal instry, Yao Jiangbo, director of land and resources, Zhang Xiaorui, head of niuchuan Township, and Zhao Xiaojun, deputy head of coal instry of Liyang Town were removed. If the relevant management departments of Jinzhong City and Heshun County, the relevant personnel of Jinneng group, and the personnel of relevant departments participating in the safety inspection of Lvxin coal instry in the near future fail to perform their ties conscientiously, the accident investigation team shall be held responsible seriously and give corresponding punishment

Learn lessons from the accident, study the causes of the accident and the problems exposed, and carry out warning ecation activities in time. Third, in the province at all levels of departments and enterprises to seriously carry out safety inspection, effectively prevent the occurrence of all kinds of proction safety accidents

9. Mine disaster refers to the accident in the process of mining, which usually causes great risk of casualties. At least thousands of people die in mine disaster every year in the world. The common mine disasters include: gas explosion, coal st explosion, gas outburst, water leakage accident, mine fire, roof collapse, etc
coal mine disaster is always the most difficult to avoid. Here we can only talk about the causes of the general mine disaster. The common problems are lax management, insufficient safety measures and facilities, and weak safety awareness, all of which are attributed to interests. Each mine disaster has its own deep reasons and particularity, so it is difficult to find a large and comprehensive web page. Typical: Fanshi mine disaster (Zhongqing Bao Liu Chang)

10. First, in the value concept of "people-oriented", in the proction of human life in the first place above all. In the past, in the age of revolution, there were always sacrifices when it was said to struggle. Today, in the age of attaching importance to human development and pursuing harmony, it is unacceptable that people die in proction because of accidents.
