Yunnan Coal Mine Policy in 217

What's the new news about Yunnan coal mines in 217? What will be the impact after the introduction of Yunnan coal mine policy? I have sorted out the policy on Yunnan coal mine in 217, I hope you like it! In 217, Yunnan Coal Mine Policy

The Yunnan Coal Mine Safety Supervision Bureau recently issued a division plan for key tasks of coal mine safety supervision in 217, which clarified 12 key points of supervision work throughout the year and printed them into a book and distributed them to every inspector.

this scheme combines the relevant requirements of the reform and development in the field of safety production and the spirit of the national teleconference on safety production, the national work conference on safety production and the Yunnan coal mine safety supervision work conference, and aims at the main contradictions and contradictions existing in the coal mine safety production work in Yunnan province in recent years, so as to realize the total number of accidents, the number of deaths and the major accidents. Three drops? For the goal, highlight the problem-oriented and goal-oriented, delimit? Six strengthening and six advancing? 12 work priorities: strengthening coal mine safety supervision and law enforcement, coal mine? Do you want to punish violations? Special actions, typical deterrence of coal mine violations, benchmarking rectification of Coal Mine Safety Regulations, safety education and training for all coal mine staff, and implementation of coal mine safety supervision responsibilities; Promote the elimination and withdrawal of backward production capacity and coal mines? One excellent and three MINUS? , coal mine safety basic work, coal mine safety risk classification management and control and hidden danger investigation and management of dual prevention and control mechanism construction, coal mine major disaster prevention and control, coal mine emergency rescue capacity building.

At the same time, the plan refines the 12 aspects of work into 6 specific tasks, which are implemented in every department and unit, and finalizes the completion time limit, standards and work quantitative indicators; By analyzing the various types of coal mines one by one and making policies according to the mines, the coal mining enterprises are defined. Must do it? And? Forbidden to do it? The relevant requirements are detailed, quantitative, concrete and operable; Emphasize the supervision of the implementation of the main responsibility of coal mine safety and the responsibility of safety supervision, and strengthen? Double investigation of one case? And joint punishment.

the introduction of the scheme can not only be used as the overall coal mine safety supervision staff? Benchmark the table? The basis of performing one's duties and responsibilities, dereliction of duty and accountability, can also play a role in supervision and even coal mine management? Reference book? The role of. In 216, Yunnan Province closed 128 coal mines.

According to the Circular, in 216, the coal mines in Yunnan Province went to capacity to promote transformation and upgrading, which was solid and effective. Keep a bottom line, clear two channels and strengthen three measures? (firmly hold the bottom line of stopping production and rectification of coal mines with an annual output of less than 9, tons, unblock the two channels of upgrading, transformation and upgrading, and voluntarily withdraw, strengthen the system of special personnel for stopping production and rectification of coal mines, strengthen the control of restoring maintenance, resuming production and rebuilding coal mines, and strengthen the three measures of propaganda, education and guidance for coal mines), and promote the transformation and upgrading of the coal industry and the work of de-capacity and control.

in 216, 128 coal mines were closed and withdrawn in Yunnan province, with a production capacity of 18.96 million tons, and 39 reserved coal mines completed transformation and upgrading. Qujing, Zhaotong and Dali closed 42, 21 and 14 coal mines respectively, accounting for 6% of the province. Pu 'er and Yuxi did not close down and quit the coal mine.

At the same time, we should innovate the supervision methods and carry out special actions to effectively prevent and contain coal mine accidents. There were 11 coal mine accidents and 2 deaths in Yunnan Province, and the number of accidents was the same as last year. No major or above accidents have occurred for two consecutive years; The death rate per million tons in coal mines is .498, which is lower than the control target of .8.

in view of the lack of understanding in some areas and coal mining enterprises, slow progress in transformation and upgrading, inadequate safety supervision, and lax inspection, Yunnan Province will strengthen comprehensive supervision of coal mine safety around the special work of comprehensive physical examination of coal mines, and strengthen the transformation and upgrading of coal industry, and the work of de-capacity and capacity control. Environmental impact of coal mine

Surface water drop

Due to the large amount of well water discharged during coal mining, the groundwater level drops, resulting in surface water drop.

staggered subsidence

due to a large amount of underground water pumping, the bearing capacity of the upper and lower floors of the mine decreases, and most of the small kiln coal wells did not take preventive measures such as reserved coal pillars in the mining process. Some small kiln coal wells even dug and destroyed the reserved coal pillars of state-owned coal mines at will, resulting in staggered strata and surface subsidence.

water pollution

the concentration of suspended solids and other pollutants in mine wastewater is high, especially the mine water flowing through the pyrite-bearing coal seam, which is very acidic. According to the sampling test of mine wastewater in Shuizaibian mining area of Nankeng Town, the average concentration of suspended solids is 28mg/L, the average concentration of chemical oxygen consumption is 53mg/L, the concentration of sulfate ion is as high as 25mg/L, and the lowest PH value is only 2.7. If this kind of mine wastewater is discharged without treatment, it will seriously pollute the surface water body, block the river and farmland channels, cause soil hardening and have a great impact on crops.

The problem of coal gangue occupation and weathering pollution

Coal gangue discharged from coal mines is generally piled up nearby. With the continuous increase of the storage capacity, the area of the yard is also expanding year by year. After weathering, rain erosion and spontaneous combustion, the weathered layer on the surface of coal gangue enters the atmosphere under the action of wind, which seriously pollutes the atmospheric environment.

vegetation destruction

coal mining needs a lot of wood, and the average consumption of pit wood is 15 cubic meters according to the output of 1, tons of coal.

The coal mining industry in the city only consumes about 1, cubic meters of wood a year. Such a large timber gap forces coal mines to purchase timber through multiple channels, which objectively encourages deforestation and makes the ratio of cultivation and logging out of balance. At the same time, due to the decline of groundwater level, the water content of surface aquifer decreases, which also affects the growth of vegetation.

Secondary dust

A considerable part of coal is transported by car, and the leakage phenomenon is very serious, and a large amount of coal is lost, which makes the street dust fly

In order to effectively prevent and control the environmental pollution and ecological damage produced in the process of coal mining, and make the ecological environment of coal mining areas gradually enter a virtuous circle, the following countermeasures and suggestions are put forward:

1. Strengthen the comprehensive management of mine wastewater and regional environment

(1) Treat existing wastewater. Repair and transform the aging and damaged wastewater treatment facilities and equipment to ensure the long-term and stable discharge of mine wastewater.

(2) treat the wastewater discharged from some abandoned mines. Although some coal mines have stopped mining, there are still mine wastewater (commonly known as old pit water) discharged. The main reason is that some coal mining tunnels are indirectly connected, and all mine wastewater is discharged from the wellhead with the lowest elevation, and iron ions in pyrite in the original old tunnel rock fault and weathering layer are leached out, resulting in high concentrations of iron ions and sulfate ions in wastewater, which seriously pollutes the water environment. Therefore, the waste water discharged from some abandoned mines must be treated, sedimentation tanks should be built, lime and other chemicals should be added to the wells, and then discharged after neutralization, reaction and sedimentation.

(3) comprehensive management of some areas with serious environmental pollution and ecological damage. First, dredging and revetment of silted rivers; Second, to do a good job in soil and water conservation projects, sewage sedimentation treatment tanks should generally be built at the confluence of surface runoff in mining areas.

Second, do a good job in comprehensive utilization of coal gangue

The main ways of comprehensive utilization of coal gangue in our city are power generation and brick making, with an annual profit of about 65, tons, but compared with the storage capacity, it can be said that the utilization amount is very small and the utilization way is single. We must try our best to explore new ways of comprehensive utilization of coal gangue, so as to realize the goal in the shortest possible time? Eliminate? Coal gangue hill. The measures that can be taken are: < P > (1) increasing the comprehensive utilization of coal gangue power generation; (2) using coal gangue instead of clay to make bricks; (3) Backfilling disposal with coal gangue: 1. Backfilling the mining area with coal gangue; 2. Coal gangue is used as engineering filling material.

Third, do a good job in vegetation restoration in the mining area and covering vegetation in the waste dump

(1) Closing hillsides to facilitate afforestation, and adopting the methods of planting grass, artificial afforestation and thinning forest to improve the ability of surface water conservation and soil and water conservation.

(2) for the coal gangue that can't be digested for a short time, formulate feasible protected plans, schemes and measures. Appropriate forests are suitable for forests, and grass is suitable for grass, so as to protect the vegetation covered with soil in the coal gangue yard.

The underground mine fire in Centralia, Pennsylvania, USA, has been burning continuously for more than 4 years since 1962, causing groundwater evaporation and stratum subsidence. Because the vein extends the whole town, cracks often appear on the ground and flames emerge. The local population has also decreased from 2, at its peak to 9 in 27.
