2016 is the beginning year of the 13th Five-Year Plan for the coal industry,

　　According to data from China Coal Industry Association and other departments,at the end of 2016,coal output was 3.45 billion tons,the number of coal mines was about 9,000,the output of large coal mines with 1.2 million tons or more accounted for 75%,and the number of coal enterprises was less than 4,000...

　　This is a starting point.So,do you know what five changes the coal industry will usher in by 2020?

　　1.Eliminate 800 million tons of backward production capacity

　　A set of data in the"Thirteenth Five-Year Plan for Coal Industry Development":

　　By 2020,the coal output will be 3.9 billion tons,the excess and backward production capacity will be eliminated and eliminated by about 800 million tons,and the advanced production capacity will be increased by about 500 million tons by reducing replacement and optimizing the layout;

　　By 2020,the number of coal mines will be controlled at about 6,000,and the output of large-scale coal mines with 1.2 million tons or more will account for more than 80%;

　　By 2020,the number of coal enterprises will be less than 3,000,and the output of large enterprises above 50 million tons will account for more than 60%;

　　By 2020,the degree of mechanization of coal mining will reach 85%,and the degree of mechanization of tunneling will reach 65%...

　　2."Three-machine"automation and mechanization of tunneling

　　It is understood that at present,the mechanization degree of coal mining in state-owned enterprises in our country is more than 90%,and the mechanization degree of tunneling is more than 80%.The mechanization degree of coal mining in small coal mines nationwide is 55%,and the mechanization degree of tunneling is even lower.

　　"Planning"pointed out that by 2020,the coal mining mechanization degree will reach 85%,and the mechanization degree of tunneling will reach 65%.

　　The chairman of the China Coal Machinery Industry Association said:"At present,China's mechanization level of digging is relatively low,and there are some gaps in the technology of integrated digging and anchoring equipment from abroad.The higher the level of mechanization,the higher the degree of safety.It is said that improving the degree of mechanization of excavation during the 13th Five-Year Plan is the focus of development."

　　3.New ways to explore coal mine utilization

　　According to the"Planning",the raw coal selection rate will reach more than 75%by 2020;the production of coalbed methane(coal mine gas)is 24 billion cubic meters and the utilization is 16 billion cubic meters;the comprehensive utilization rate of coal gangue is about 75%;the utilization rate of mine water is 80%About;land reclamation rate is about 60%.

　　Regarding the utilization rate of mine water,there are currently two main destinations for mine water:one is the development of coal chemical industry in the western region,and the other is used by power plants constructed by coal mines.In 2016,the utilization rate of mine water in China was 70.6%.

　　The"Planning"clarifies the overall national coal development plan of"compressing the eastern,central and northeastern,and optimizing the western region",which has a certain effect on improving the utilization rate of mine water."The main production areas are going west,the mine water inflow in the west is less than that in the east,and the total water inflow is reduced."The chairman of the China Coal Processing and Utilization Association said,"The mine water utilization rate will increase during the 13th Five-Year Plan period."

　　4.Substantial compression of coal mine construction

　　In accordance with the requirements of eliminating outdated production capacity and not building new coal mines within three years,it challenges the field of coal mine construction.

　　The secretary general of the China Coal Construction Association said:"Construction projects have decreased and the mining construction market has shrunk.Currently,40%of mining construction projects are basically gone,and coal mine construction is facing a transformation."

　　According to the prediction of the Secretary-General,the proportion of coal mine construction will be reduced from 70%at present to 30%by 2020.

　　5.The coal industry decreased by 1.5 million people

　　At the beginning of 2017,China's coal employees were about 4.5 million.It is understood that if all the 800 million backward production capacity is eliminated,1.5 million coal employees will need to be reduced.

　　It is understood that the United States produces 1 billion tons of coal and requires 100,000 coal employees.Even by 2020,China produces 3.9 billion tons of coal,and there are still 3 million coal employees.Compared with developed countries,the gap still exists.

　　The Director of the Policy Research Department of the China Coal Industry Association believes that the ideal number of people producing 4 billion tons of coal is 1.5 million.This involves the way out for one or two million people,and it must be solved gradually.We are facing world competition and we must solve human problems.Too many people produce coal,and efficiency is not high,so this industry has no prospects.
