矿区污染等级划分与环境综合治理分区
Pollution Level Classification and the Comprehensive Partition in Mining Area

采用层次分析法，计算矿区内的企业(包括露天煤矿、井工煤矿、石灰厂、硅石厂、洗煤厂、焦化厂、水泥厂、石料厂和铁矿厂)的加权总产污量，全面评价矿区内企业的污染程度。利用污染程度、风频和距离城镇的远近，将矿区划分为四个区块，并制定了相应的治理和预防机制。为矿区环境污染防治工作提供科学依据和指导。
Using analytic hierarchy process, the weighted total pollutant amount of mining enterprises ( in-cluding opencast coal mine, coal mine, lime plant, silica plant, coal preparation plant, coking plant, cement factory, stone material factory and iron ore plant) is calculated to evaluate the compre-hensive pollution degree of the mining enterprises. Pollution degree, wind frequency and the dis-tance from the town are used to divide the mining area into four parts. The results can provide a scientific basis for environment pollution prevention.
