郭家河煤矿主要隐蔽致灾地质因素分析

Analysis on Main Concealed Disaster-causing Geological Factors in Guojiahe Coal Mine

综合分析了郭家河煤矿以往勘查成果,结合郭家河煤矿矿井生产建设过程中所获得的各类地质资料,对矿井隐蔽致灾地质因素进行分析研究,得出主要隐蔽致灾地质因素有离层水、冲击地压、瓦斯、采空区和封闭不良钻孔等,为矿井及时处理地质灾害,有效预防煤矿事故提供了依据。

Based on the comprehensive analysis of the previous exploration results of Guojiahe Coal Mine and the various geological data obtained in the process of production and construction of Guojiahe Coal Mine,the geological factors causing hidden disasters in the mine were analyzed and studied.It was concluded that the main geological factors causing hidden disasters are separated layer water,rock burst,gas,goaf and bad-closed boreholes.It provides a basis for dealing with geological hazards in time and preventing coal mine accidents effectively.
