摘　　要：为了快速、全面的查明炭灰沟煤矿主要隐蔽致灾的类型、空间分布特征,分析其对煤矿的潜在威胁;采用现场质询、资料查阅、周边煤矿调研、地表无人机可见光+热红外成像快速扫面、地面踏勘、井下调查和探测等方法,对煤矿进行天空-地面-井下全方位排查,排查分析出影响煤矿安全生产的水害因素主要有庙沟地表水、老空水、顶板砂岩水、封闭不良钻孔;火灾因素有1-2煤房柱式采空区及井巷遗煤、地面塌陷裂缝等;顶板/矿压相关致灾因素主要有坚硬顶板、房采区悬顶、孤岛工作面等;研究分析了各隐蔽因素对煤矿的潜在威胁。In order to quickly and comprehensively find out the types and spatial distribution characteristics of the main hidden disasters in Tanhuigou Coal Mine and analyze its potential threat to the coal mine,the methods of on-site inquiry,data access,investigation of surrounding coal mines,rapid scanning of surface unmanned aerial vehicle(UAV)visible light+thermal infrared imaging,ground reconnaissance,underground investigation and detection were adopted to conduct all-round sky-ground-underground investigation of the coal mine.The water hazard factors affecting coal mine safety production are found out,including Miaogou surface water,old empty water,roof sandstone water,and poorly sealed drilling holes;the fire factors include 1-2 coal room pillar goaf,residual coal in mine roadway,ground collapse cracks,etc.The disaster-causing factors related to roof/ground pressure mainly include hard roof,roof hanging in room mining area,isolated working face,etc.The potential threats of hidden factors to coal mines are studied and analyzed.
