摘 要: 准确地厘定矿山环境影响范围和程度,才能有效地开展矿山环境保护与综合治理.以水文地质学与矿山环境评价相关理论为基础,深入广致煤矿现场,复核矿山地质环境条件,详细分析矿山环境问题现状.基于矿业活动过程中的安全开采深度、上下山移动角和边界角以及地下水均衡理论,系统地分析和计算广致煤矿采掘活动对矿山环境的不同类型影响范围:利用上下山移动角确定地质灾害危险性影响大区、上下山边界角划定井下开采影响范围和采用地下水位降落漏斗"大井法"定出矿区疏排水影响范围.开展矿山环境影响预测与综合评估,同时,依据矿山环境问题类型影响程度,相应地将其划分为矿山环境影响严重区、较严重区和较轻区三大类,并给出其量化指标.研究成果为广致煤矿开采过程所导致的矿山环境综合治理提供依据. The protection and integrated management of mine environment can be carried out effectively,if the coverage and degree of the influence of mine environmental be accurately delimited.Based on the theory related to hydrogeology and mine environment evaluation by in-depth research on the site of Guangzhi coal mine,mine geological environment conditions were reviewed,current situation and existing mining environmental problems were analysed detailed.Based on the safe depth of mining,displacement angle,boundary and the theory of groundwater balance in the process of mining industry activities,several different types of area of influence of mine environment that was induced by mining activities were analyzed systematically,such as huge geological hazard region of influence is determined by up-dip and down-dip displacement angle.the area of influence by mining is determined by up-dip and down-dip boundary angle,area of influence by drainage is determined by big well method of cone of exhaustion.Prediction and integration assessment of mine environment influence were developed,Meanwhile according to the types of geological environment problem and the degree of influence,the coverage of influence of mine environment was divided into three areas: serious,more serious and lighter,and the quantitative indicators were given.The integrated management basis for reference is provided for the environment problems of the Guangzhi coal mine.
