China’s recoverable reserve of coal is 114.5 billion tons,—20.75% of the gross in the world, but crude oil and natural gas are only 1.50% and 1.12% of the world respectively.

2005Production:2.20 billion tons76.4% of the totalconsumption:2.17 billion tons68.9% of the total
1 The amount of proposed projects increases fast
1998-2002: no large coalmine constructed due to the Southeast Asian financial crisis2003: new coalmine construction upsurge began, 144 environmental impact reports submitted to ACEE , the investment exceeded the past 50 years Totally 248 billion RMB2007: the investment begin to fade away

2 The distribution is regular129 proposed projects distributed in Inner Mongolia, Shanxi, Shaanxi, Xinjiang, Guizhou, Ningxia, Anhui, Shandong and Henan. the capacity reached 0.66 billion tons, 93.4% of the total.
3 integrated with correlative industries
Planned economy: coalmine——Ministry of Coal Industry electric power——Ministry of Power Industry chemical industry——Ministry of Chemical IndustryMarket economy: Department and regional monopoly was broken Coal exploitation, electric power and coal chemical industries are integrated both on the enterprises and regional level Many traditional coal mining groups expand toward electric power and coal chemical field
• Subsiding area :103 km2 /a , totally 5,150 km2
• Excavating area by 14 opencast mines: 700km2 • Land occupation by coal slack : 9.87 hm2 per
coalmine, totally 14 km2
• Impact: water and soil loss, desertification ,the loss of biodiversity , the loss of farmland
1 The ecological impact
2 Water resource pressure
Distribution of coal resource and water resource is reversed.98 coal mines are with in 100 km from the main rivers.69 coal mines concentrated in Yellow Drainage basin.
Water consumptionElectric power:1000kw·h ↔3.63 tons Coal chemical industry: 1 ton product ↔ 10 tons.

some coal mines’ subsiding impact in Huainan Mining Group
Once the depth of subsidence exceeds that of groundwater, the subsiding land will be turned into water area forever and the ecological framework will be changed.
4 The waste influence
Actuality: Solid waste: more than 1,500 coal slack hills (only state-owned coalmines), accumulating quantity reached 3.85 billion tons. The reusing level is only 42%. Waste water: 4.5 billion tons discharged per year. The reusing proportion is only 48.95%. Coal-bed gas: 14 billion cubic meters was discharged every year, only 24.4% is used from the quantity pumped out.
1 The SEA lags behind the practical need
Environmental Impact Assessment Law was issued in 2003, including plans and projects. But the EIA towards coal district plan haven’t developed universally.
Obstacles: negligence of the government lack of the money conflict of the ministerial benefit
2 The management policy isn’t clear
Environment policies seldom consider the regional differences
Policy of eco-environmental protection and the pollution prevention: reusing level of waste water for large coalmines should be at least 65%, the reusing proportion of coal slack should be at least 55%, and the reclamation rate of the influenced land should reach 75% till 2010. It is not reasonable to set the same criteria.
3 Migrating problem hasn’t aroused enough attention

4 The ecological compensation mechanism is absent
The environmental externality hasn’t been considered sufficiently. There is no uniform ecological compensation mechanism in the coal industry.
Four key problems: compensation criteria compensation entity compensation way supervision mode
1 Accelerating the implementation of SEA
SEA Should focus on systematic ecological renovation reuse of the waste migration protection of sensitive objectives
The EIA towards projects has been implemented universally, but the SEA upon plans of coal district has just been put into practice no more than 5 years.
The typical zones for environment management
1 、 Loess plateau hilly and gully zone2 、 Plan mine-grain complex zone3 、 Yunnan-Guizhou mountainous zone4 、 North-west desert grassland zone
5 、 East Mongolian meadow grassland zone
3 Arranging the migration comprehensively
The migration offered an opportunity of promoting the urbanization level and adjusting the framework of economy and society.

4.4 Installing the ecological compensation mechanism
Three types of compensation Enterprise to local Coal inflowing region to the out flowing regionState to the historic remaining problem
As the most important resource exploitation sector, coal industry should install the compensation mechanism in priority.
