【摘要】 基于采掘揭露资料、钻探数据、物探及相关试验成果,采用实地调查、井下观测、统计分析等方法,分别对研究区地质构造、地下含水体、导水裂隙带、采空区、瓦斯富集区、封闭不良钻孔、井下火区等矿井隐蔽致灾因素进行详细研究,确定矿井主要隐蔽致灾因素,并进一步结合各隐蔽致灾因素特征提出针对性防治措施。研究表明:林西矿主要隐蔽致灾因素为断层、岩浆岩、奥陶系灰岩含水体、采空区,这些因素不同程度地威胁着矿井安全生产,需采取有效的防治措施,合理安排治理隐蔽致灾计划,为防治矿井隐蔽致灾因素提供可靠依据。

【Abstract】 Based on the data of mining exposure,drilling,geophysical prospecting and relevant test results,this paper selected Linxi mine as object to study the hidden hazard factors including the geological structure,underground aquifer,water flowing fractured zone,mining goaf,gas- rich zone, poor sealed boreholes and underground fire zone by field survey,underground observation, statistical analysis and other methods, and the pertinent prevention measures were proposed. The results showed that the faults,magmatic rocks,Ordovician limestone aquifer and mining goaf were the main hidden hazard factors in Linxi Mine,threatening the mining safety in different degree. Therefore,effective measures and reasonable plan shall be prepared against the hidden hazard factors.
