摘要
通过开展煤矿隐蔽致灾地质因素普查,为盛鑫煤矿灾害防控提供科学依据。通过资料收集、调查访问并结合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)、地质构造、陷落柱、瓦斯富集区、导水裂缝带、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,查出矿井主要隐蔽致灾地质因素。同时根据隐蔽致灾因素评价的结果和盛鑫煤矿存在的问题,制定防治治理计划和防范措施,提升煤矿安全保障能力。
Through the general survey of geological factors of concealed disasters in mines, a scientific basis for disaster prevention and control in Shengxin Mine was provided. Through data collection, survey visits and combined with the actual disclosure in the production process and the comprehensive analysis of indoor data were conducted to investigate the goaf,abandoned old kiln(wellbore), closed poor borehole(or unclosed borehole), geological structure, collapse column.Geological factors such as gas enrichment area, water-conducting fracture zone, groundwater body, underground fire zone,ancient riverbed scouring zone and skylight were investigated to find out the main concealed geological factors of the mine.At the same time, according to the results of the evaluation of hidden disaster factors and the problems existing in Shengxin Mine, the prevention and control plan were formulated to improve the safe of coal mines.
