Muli coal are featured by natural resources of biological his germinal the qinghai-tibet plateau, mining widely distributed in the swamps. the present reflections featured in the development and utilization of mineral resources Muli coal promote economic development, but also for Muli coal geologic and ecological environment has a great impact, sideband a series of geological environmental problems. the geological environmental problems to Muli coal of geological environments cause serious damage, and indirectly lead to the yellow and yangtze river and lancang jiang lower-middle reaches of the people in production and living are seriously threatened . Accordingly, Muli coal Juhugeng two bed on the geological and environment quality evaluation of great practical significance.Firstly, according to the connotation of bearing capacity of the geological environment, the article select the wetland environment index, permafrost thawing grade, geological structure and other indicators of level 9 from the natural ecological conditions and the geological environment. After determining weights of the index layer through the AHP ,using integrated index to evaluate and analyze the carrying capacity of geological environment for the Muli coal Juhugeng two bed.And from the three areas of regional geological environment, geological disasters and mining-induced environmental and ecological problems selected terrain, mud sliding into the situation, thaw settlement, grass marsh degradation, permafrost and destruction of 11 factors as the quality evaluation of the geological environment factor, using AHP to determine the weight of each factor, after building evaluation model, using fuzzy comprehensive evaluation method of geological analysis to evaluate environmental issues, the geological environment quality of Juhugeng two bed are classified as serious, less serious and general three level. Finally, integrated capacity of the mine geological environment evaluation of level and quality of geological environment, the article come to evaluation of zoning map for Muli coal Juhugeng two bed. from two aspects of policy and engineering measures the article put forward to reasonable control countermeasures.The result indicate combination Capacity of geological environment evaluation and geological integrating environmental quality evaluation more to help understand the development of mining featured in the swamp the wet district level in Muli coal, For mineral exploitation of Muli coal has a strong sense of direction.
