摘　　要：贵州山区地质环境脆弱,煤矿开采易引发地质灾害。为使煤矿业主充分认识到可行性研究阶段开展地质灾害危险性评估工作的目的与意义,以某煤矿为例,结合其地形条件、煤层赋存条件及开采方案设计,采用赤平投影、稳定性检算、数值模拟等方法对开采前后不同工况下山体的稳定性进行了直接、间接的影响分析,结果表明该煤矿开采后引发地质灾害的可能性大,治理地质灾害的难度大、投资额高,项目的投资可行性较差。进而得出应将地质灾害危险性评估报告的主要结论纳入可行性研究报告或在可行性研究报告中增加专门篇章的结论。The mountainous region of Guizhou has a fragile geological environment,making it susceptible to geological disasters when coal mining activities take place.This study aims to emphasize the importance and significance of conducting geological hazard risk assessments during the feasibility study stage of mining projects.Using a specific coal mine as a case study,and considering its topographical features,coal seam deposition,and proposed mining designs,we employed methods like stereographic projection,stability analysis,and numerical simulation.These methods helped in evaluating both direct and indirect impacts on mountain stability under different mining conditions.Our findings suggest a high probability of geological disasters post-mining,indicating challenges in disaster mitigation,increased associated costs,and a subsequent lack of investment feasibility.Therefore,we recommend incorporating the primary conclusions of geological hazard risk assessments into the main feasibility study report or adding a dedicated section addressing these findings.
