摘　　要： 为准确划定矿山环境影响范围,有效地开展矿山环境保护与综合治理,促进矿山可持续发展,本文在详细分析贵州平坝榜上煤矿矿山环境现状存在问题的基础上,运用采掘活动过程中的安全开采深度、移动角、边界角和地下水均衡原理等理论,系统地分析和计算了榜上煤矿矿山环境影响的几类不同范围:利用上山移动角确定地质灾害危险性大区,采用边界角确定井下开采影响范围,运用"大井法"圈出疏排水影响范围。依据矿山环境问题类型影响程度,相应地划分为严重区、较严重区和较轻区等3类,并给出具体量化指标。 In order to delimit the mine environmental influence range accurately, carry out mine environment protection and comprehensive treatment effectively, and promote mine sustainable development, based on detailed analysis of existing problems of mine environment status quo in the Bangshang coalmine, Pingba County, Guizhou Province, the paper using theories of safe working depth, angle of draw, boundary angle, and groundwater balance during mining work activities, systematically analyzed and computed some different ranges of mine environmental influence in the coalmine. Using rise heading angle of draw delimits geological hazard region, boundary angle delimits area of influence, ＂virtual large diameter well＂ method delineates influence area of drainage. According to influence of mine environment problematic types has correspondingly divided into very serious area, serious area and minor area three categories and gave out concrete quantizing indices.
