摘　　要：结合伯方煤矿实地工程,根据3209工作面具备的开采地质条件,研究分析确定该工作面主要冲击影响因素,同时通过多因素叠加法对3209工作面回采过程中可能出现冲击危险区域进行划分,经评价之后确定保护开采技术,以此达到煤矿在安全开采情况下提高采出煤炭量、减少资源浪费、提高整体煤炭采出率、提高资源利用率及节能环保的目的。Based on the on-site engineering of the Bofang Coal Mine and the geological conditions of the 3209 working face,the main impact influencing factors of the working face are studied and analyzed.At the same time,the multi-factor superposition method is used to divide the potential impact risk areas during the mining process of the 3209 working face.After evaluation,protective mining techniques are determined to improve the coal output and reduce resource waste under safe mining conditions.The goal is to improve the overall coal extraction rate,resource utilization rate,and energy conservation and environmental protection.
