邯郸矿区矿山地质环境承载力评价

Evaluation on the carrying capacity of coal mining geo-environment in Handan mining area

依据矿山地质环境承载力的涵义及特点,从地质环境抗扰动能力和煤炭开采压力两个方面,建立矿山地质环境承载力评价指标体系,利用层次分析法确定指标权重值.对邯郸矿区进行系统的矿山地质环境承载力评价研究,研究结果显示:不同矿井的矿山地质条件、开采方法、开采技术水平及对环境的保护力度有差异,矿山地质环境抗扰动能力和煤炭开采压力有差异.研究结果对矿业开发、地质环境保护与恢复治理具有实用价值.

The evaluation of carrying capacity of mine geo-environment is an important topic in the evaluation of mine geo-environment.According to the definition and level characteristics of carrying capacity of mine geo-environment,based on the geo-environment resistance to disturbance and coal mining pressure,this study had developed an evaluation index system of carrying capacity of mine geo-environment,and determined the index target weight using AHP.In a case study,a systematic study of carrying capacity of mine geo-environment was conducted at Handan coal mine area.The results of the study show that the environmental protection efforts for different mines vary with mine geology conditions,mining methods,and mining technology level.Also,there is a difference in geo-environment resistance to disturbance and coal mining pressure.This study provides a scientific basis for developing mining industry,protecting and restoring geological environment.
