山东某煤矿工作面的冲击危险性分析与研究

Analysis and Study of Impact Hazard at a Coal Mine Working Face in Shandong

山东某煤矿煤层已经鉴定为具有强冲击倾向性的煤层,结该煤矿地质条件和开采技术方案,对该工作面的冲击危险性进行分析。根据工作面冲击地压危险性的分析与研究,表明该工作面巷道存在弱冲击危险区9个,对指导该工作面防治冲击地压灾害方案的制定、防治设计参数的确定、保障安全生产具有重要意义。

The coal seam of a coal mine in Shandong has been identified as a coal seam with strong impact tendency,and the impact hazard of the working face is analysed in relation to the geological conditions and mining technology scheme of the coal mine.According to the analysis and study of the impact hazard of the working face,it is shown that there are nine weak impact hazard zones in the working face roadway,which is of great significance to guide the formulation of the prevention and control plan of the impact hazard of the working face,the determination of the prevention and control design parameters,and the guarantee of safe production.
