How can I get to lianghuangshan from Ninghai passenger transport
(1) organic pollutants. The decay of plants in mine waste water pool and tailing pool may make the content of organic components in waste water very high. The waste water discharged from concentrator, coal washing plant and analysis laboratory contains organic compounds such as phenol, cresol and naphthol, which are extremely harmful to aquatic organisms
(2) oil pollutants. Oil pollutants are common pollutants in mines. Oily wastewater is immersed into the pores to form oil film, which causes blockage, damages the soil structure, is not concive to the growth of plants, and even makes crops wither. The existence of oil film on the water surface hinders the transfer of oxygen from the atmosphere to the water body, resulting in the lack of oxygen in the water body and the death of aquatic organisms e to lack of oxygen
(3) acid and alkali pollution. Acid and alkali pollution is a common phenomenon in water pollution. When acid and alkali wastewater is discharged into water, the pH value of water will change, the growth of bacteria and microorganisms will be inhibited, water self purification will be hindered, ships and hydraulic structures will be corroded, and the normal ecological cycle will be destroyed
4) oxides. The oxide is highly toxic. Most people will die if they take about 0.1g of sodium cyanide or potassium cyanide by mistake. Sensitive people can even die at 0.06g. When the content of CN - in water reaches 0.3-0.5mg/l, the fish will be killed

According to the statistical data of the national mine geological environment survey and assessment project, the total number of mines in China is 132.25 million. The total number of mines in Northeast China, North China, East China, South China, Southwest China and southwest China is 135030, 40360000, 26610, 1992300, 1076500 and 210730 respectively (table 5-1-1)
table 5-1-1 number of mines in China. Due to the lack of understanding in the early stage and the guidance of wrong ideas, we only paid attention to economic interests and sacrificed environmental resources, resulting in the waste of mineral resources. Since the reform and opening up, a large number of private new mines have been pouring out, which makes the mine geological environment problems present a scattered and universal trend. With the accumulation of old mine geological environment problems and the destruction of new mines, the mine geological environment problems have evolved from local point destruction to regional geological environment problems, affecting the safety of human settlements and the quality of life
before the mineral procts are consumed, the mining, processing, transportation, trading and use of mineral procts are generally completed. In each link, it is possible to cause environmental pollution and damage, especially in the mining process, the degree of damage to the environment is the largest, and it is also the link that causes the most environmental problems
At present, the common classification of mine geological environment problems is as follows:(1) three wastes pollution: solid waste pollution, water pollution and air pollution
(2) resources damage: water resources damage, land occupation, land function degradation (soil erosion, land desertification), seawater intrusion, etc (3) geological disasters: collapse, landslide, debris flow, ground fissure, ground collapse, ground subsidence, mountain cracking, etc Solid waste pollution in the process of mining, the main wastes are waste rock, tailings and so on. The long-term accumulation of waste not only occupies a lot of land, but also causes st, spontaneous combustion and other waste gas pollution. Coupled with the scouring and leaching of perennial rainfall, many harmful components enter into the soil and surface water, causing soil pollution and water pollution problems, and bringing unsafe factors to the living environment around the mining area
table 5-1-2 proction and discharge of mining solid waste in China
2. Air pollution
the main sources of air pollution are st, spontaneous combustion of gangue and volatilization of harmful gases. Exposed to the surface of the accumulation, under the action of climate, prone to spontaneous combustion, explosion and other structural changes, gas release and surface composition weathering into the atmosphere. And it is easy to cause secondary pollution such as acid rain
3. Water pollution
water pollution mainly comes from the discharge of mine water, followed by the leachate from waste rock heap leaching, as well as the discharge of mineral processing, smelting wastewater and tailing pond water. These wastewater contain a large number of heavy metal ions, acid ions, and some are accompanied by oil pollution. Generally, they are discharged directly without treatment, causing serious pollution to surface water and groundwater
the pollution of groundwater is generally limited in the vicinity of the mine, which is caused by the leaching and infiltration of waste water, slag and tailings or the infiltration of polluted surface water
table 5-1-3 exhaust gas emission of mining instry in China
table 5-1-4 discharge and treatment of mining wastewater in China
(2) resource damage1. Mining destroys a large amount of land resources
the land occupied by mining instry destroys land resources, among which the occupied land refers to the land affected by proction, living facilities and development and the land occupied by transportation serving the mine; Among them, the damaged land refers to the land area damaged by open-pit mining, mping, tailing, subsidence and other mine geological disasters
According to statistics, a large mine occupies an average area of 180000-200000 m < sup > 2 < / sup >, and there are tens of thousands of square meters of small mines More than 85% of China's annual instrial solid waste emissions come from mining. At present, there are more than 1500 gangue mps in state-owned coal mines in China, with annual accumulation of 300 million tons, covering an area of 5000 HM < sup > 2 < / sup >. The total amount of tailings is about 2.5 billion tons According to incomplete statistics, up to 2003, 560665hm < sup > 2 < / sup > of land occupied and damaged by mining development in some provinces and regions of China, including 43815hm < sup > 2 < / sup > for tailings stacking, 144240hm < sup > 2 < / sup > for open pit mining and 244713hm < sup > 2 < / sup > for mining subsidence. Waste rock and tailings discharge arbitrarily, not only occupy land, pollute soil, water and air, but also cause vegetation damage and ince geological disastersShanxi, Liaoning, Jilin, Heilongjiang, Hunan, Yunnan and other provinces have more serious land occupation
2. The destruction of water balance system
the drainage damages the balance system of surface water and groundwater, resulting in a large area of drainage funnel, dried up spring water, graal depletion of water resources, river water cut-off, surface water infiltration or pouring into the underground through collapse and other phenomena, affecting the ecological environment of the mining area. Due to the continuous development of drainage funnel in some mines in coastal areas, when its boundary reaches the sea water level, it is easy to cause seawater intrusion
Land function degradationmining activities, especially open-pit mining, destroy a large number of vegetation and hillside soil, resulting in loose stripped materials such as waste rock and slag, which can easily lead to soil erosion in mining area
drainage and underground goaf destroy the water balance system, the ground is short of water and the vegetation is dry, which leads to the trend of desertification
In addition, mining engineering and pit drainage make the balance between groundwater head pressure, mine pressure and surrounding rock out of balance, resulting in a series of environmental engineering geological problems. For example, roof caving and collapse of underground goaf, floor bulging of roadway, sliding of open pit slope and water gushing of mine pit can cause serious harm The destruction of surface landscape by mining is mainly manifested in the destruction of natural landscape, landform, topography, geological relics, land and surface vegetation by its development activities, and the pollution and erosion of surface landscape and geological relics by wastes(3) geological disasters inced by mining. Open pit mining will destroy the soil structure and ecological environment. In the time of climate change, landslide, debris flow, collapse and other geological disasters will be caused by wind or rain. And it is easy to cause underground mining to destroy the underground geological structure and groundwater balance. Under the action of rain or geological conditions, it is easy to cause ground collapse, ground fissures and other geological disasters
There are more than 180 ground collapses caused by mining in China, including 1600 collapse pits with a collapse area of 1150km. There are nearly 40 mining cities with mining collapse disasters in China, 25 of which are serious. Every year, the economic loss caused by the ground collapse caused by mining alone is more than 400 million yuanTo the canine Association, they are CKU and ngkc
Professional ships and skills are needed to dig Kiev fault rock, otherwise it will bring devastating disaster to the mining team
