第一段：Wanxing annual production capacity of 90,000 tons coal capacity expansion of technological environmental impact assessment。
第二段：Wanxing Yongchuan Chongqing coal mine located in the town of the district Wanshou, the original annual production capacity of 30,000 tons，K2 coal mining, using underground mining methods; technological expansion of mining remain unchanged after the increase K8 coal, the production scale for the annual production capacity of 90,000 tons. The graduation project is aimed at technical Wanxing mine expansion project to conduct an environmental impact assessment.
The process of coal mining on water, air and sound have a certain impact on the environment, but its main impact on the local ecology.The purpose of this subject after the coal mining for the technical conduct an environmental analysis and environmental impact prediction and assessment of pollution in the corresponding response options and compensatory measures for ecological restoration.Taking environmental protection measures, the mining resources of the use of solid waste, zero emissions; coal emissions control pollutants: COD to 1.447t / a, S to 0.423t / a; cleaner production evaluation index for 88.38 in line with the national cleaner production enterprise level.
Comprehensive evaluation of the data and forecasts from the Environmental Protection point of view that Wanxing annual production capacity of 90,000 tons coal mine expansion project workable technical.

The first section 9 million tons of coal, WanXing technical capacity of environmental impact assessment
The second section: WanXing YongChuan located at chongqing coal WanShouZhen area, the scale of production for yearly produces 3 tons of coal, mining, underground mining K2 way, After the expansion of transformation of exploitation, increase production scale, the K8 seam of 9 million tons. The graduation design is WanXing technical extension project in coal mine environmental impact assessment.
Coal mining process of water, air and will sound environment impact, but its main effect to the local ecological effect for. The purpose of this topic in coal mining technology for environmental status after analyzing and predicting and evaluating environmental impact, put forward the corresponding countermeasures of pollution and ecological restoration compensation scheme. In environmental protection measures adopted after mining solid waste resource utilization, emissions to zero, Coal pollutants control indicators: COD for 1.447 t/a, S for 0.423 t/a, Comprehensive evaluation index of cleaner production 88.38 with cleaner production enterprises, domestic level.
Comprehensive evaluation, and forecast the data from the Angle of environmental protection WanXing think of nine tons of coal project feasible technical capacity.
