摘要
隐蔽致灾地质因素普查对矿井安全生产具有重要意义。结合西曲矿地质勘察成果和生产建设过程中的各种地质资料,综合分析矿井各类隐蔽致灾地质因素,得出西曲矿主要隐蔽致灾地质因素有小窑老空水、陷落柱、防水密闭、风氧化带和黄泥带,为矿井预测预报地质灾害,预防煤矿事故的发生提供依据。经分析认为,该矿应着重加强小窑资料的收集工作,同时利用地面物探、施工地面勘探孔、井下物探和钻探等技术手段对小窑破坏区、陷落柱、风氧化带和黄泥带进行进一步勘查。针对防水密闭需绘制防水密闭巡查图,对防水密闭进行逐个排查。
The geological survey of hidden disaster-causing geological factors is of great significance to mine safety production.By analyzing the geological exploration results and various geological data in the process of production and construction in Xiqu Coal Mine,it is concluded that the main disaster-causing geological factors in Xiqu Coal Mine are goaf water in small mine,collapse column,waterproof sealing,wind oxidation zone and yellow mud zone,which provides the basis for the prediction of geological disasters and the prevention of coal mine accidents.The analysis shows that the data collection of small mines should be strengthened,the destruction area of small mines,collapse column,wind oxidation zone and yellow mud zone should be further prospected by means of surface geophysical exploration,surface exploration borehole,underground geophysical exploration and drilling,the inspection map of waterproof sealing should be drawn,and the waterproof sealing should be checked one by one.
