How much is going to the talent center for social security
The proction practice shows that, compared with other mining methods, the filling mining method has the following advantages: (1) the cutting quantity is small and the flexibility is large 2) The ore loss and dilution are small 3) It can effectively maintain the surrounding rock, rece the movement of surrounding rock and prevent a large number of caving 4) For thin vein or multi variety ore, it can be separated and mined 5) It can prevent the internal fire caused by mining 6) Waste rock and tailings can be used as filling materials 7) Controlling surface subsidence 8) Improve underground mining environment. The main disadvantages of filling method are: the mining process and filling process are complex, and the mining and filling interact with each other. If the mechanized mining operation can not be properly solved, the proction efficiency and capacity are low. In addition, the mining, processing, transportation and other costs of filling materials, the raw ore cost is high
1. Different concepts
mining instry is the basic instry of national economy. At present, 93% of China's energy, 80% of instrial raw materials and 70% of agricultural means of proction come from mining procts. The development of mining instry provides rich mineral raw materials for various departments and plays a supporting role in the development of national economy
Mining refers to the extraction of naturally occurring minerals such as solids (such as coal and minerals), liquids (such as crude oil) or gases (such as natural gas). It also includes the preparation needed to make the raw materials available for sale. But it does not include water storage, purification and distribution, as well as geological exploration and construction activities
2. Different characteristics
the characteristics of the mining instry are that it takes the natural materials in nature as the labor object, and its procts are the necessary raw materials for the manufacturing instry; The construction period is long, the investment is large, and the proct transportation is large; The mineral resources are limited. In order to develop the mining instry, we must consider its resources, reserves, grade, occurrence conditions and their distribution, the urgent need of the country, and the geographical location of transportation, so as to determine its reasonable mining scale, service life and development time sequence
The characteristics of mining instry are mainly shown in the following aspects: the proportion of various mining methods, mining technology and technical equipment have changed greatly; they are all developed along the direction of high efficiency, high recovery rate and mechanization; the stope proction capacity and labor proctivity have been greatly improved; the loss and dilution index have been greatly reced. At present, the main mining methods are filling mining method, open stoping mining method and caving mining method Mining instry is an instrial sector that directly exploits all kinds of raw materials and fuels from nature, mainly including the mining of all kinds of metal and non-metal minerals (such as coal, iron ore, oil and natural gas, chemical minerals, etc.), wood cutting, proction and supply of tap water, etcthe mining instry includes underground or above ground mining, mine operation, and all auxiliary work for processing raw materials, such as grinding, beneficiation and treatment, which are generally carried out at or near the mine site

the full name of a driver's license is a motor vehicle driver's license, also known as a "driver's license", which is required by the law for motor vehicle drivers
driving a motor vehicle requires certain driving skills. If people lack such skills, they may have traffic accidents if they drive a motor vehicle at will, and most people can't drive on the road without a license. But for those who have the safe driving skills, they are allowed to drive on the road. This kind of permit is called "driving license". This shows that the driver's license is a kind of "permit"
