某煤矿隐蔽致灾地质因素研究

Study on Geological Factors of Hidden Disaster in a Coal Mine

通过对煤矿隐蔽致灾地质因素开展普查工作,为煤矿安全生产提供科学依据。本文通过以往资料收集、调查访问、生产过程中实际揭露情况和室内资料综合整理、分析,对采空区、废弃老窑(井筒)、封闭不良钻孔(或未封闭钻孔)、断层、裂隙、褶曲、陷落柱、瓦斯富集区、导水裂隙带、地下水体、井下火区、古河床冲刷带、天窗等地质因素进行普查,查明了矿井主要隐蔽致灾地质因素。同时根据隐蔽致灾因素普查的结果和煤矿存在的安全问题,制定防范措施和防治治理计划,提升煤矿安全生产的保障能力。

This paper provides scientific basis for coal mine safety production by conducting general survey of hidden geological factors causing disaster.Based on the previous data collection,investigation and interview,the actual exposure in the production process and the comprehensive arrangement and analysis of indoor data,the geological factors such as mined-out area,abandoned old kiln(shaft),poorly closed borehole(or unclosed borehole),fault,fissure,fold,collapse column,gas-rich area,water-conducting fissure zone,underground water body,underground fire area,ancient riverbed erosion zone and skylight are investigated,and the main hidden geological factors causing mine disaster are identified.At the same time,according to the results of the survey of hidden disast-causing factors and the safety problems in coal mines,preventive measures and prevention and control plan are formulated to improve the guarantee ability of coal mine safety production.
