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.
Accurately determine the scope and extent of mine environmental impact in order to effectively carry out mine environmental protection and comprehensive management.With the theory of hydrogeology and mine environmental assessment as the foundation, go deep into the coal mine site, review the geological conditions of the mine, a detailed analysis of the mine environment Based on the safe mining depth, the up and down movement angle, the boundary angle and the groundwater equilibrium theory, this paper systematically analyzes and calculates the different types of influence range of coal mining activities on the mine environment: using the up and down movement angle to determine The impact of geological hazards in large areas, the upper and lower boundary of the mountain area to draw the scope of the influence of downhole mining and the use of groundwater level fall funnel “big well method ” to determine the impact of drainage and drainage of mining areas to carry out mine environmental impact prediction and comprehensive assessment, at the same time, The influence degree of mine environmental problems types, and accordingly it is divided into three major categories of serious environmental impact areas, serious and light areas, and its quantitative indicators are given.The research results are as follows: Provide a basis for comprehensive management.
