红石岩煤矿隐蔽致灾因素分析

为保障煤矿安全开采,有针对性地制定预防和治理措施,对红石岩煤矿隐蔽致灾因素进行探究。首先梳理了红石岩煤矿已揭露的地质情况和现有的钻探、物探和水质化验成果,瓦斯鉴定等资料,结合煤矿隐蔽致灾因素具有隐蔽性、时变性、突发性、难探测和难预防的特点,对其地面和井田内的采空区、废弃老窑,钻孔、地质构造、地下含水体、瓦斯和煤层自燃及煤层顶底板等因素进行了分析。总结出该矿主副井筒周边采空区水、因采动影响产生的顶底板导水裂隙带等主要隐蔽致灾因素,以及断层的活化和滞后出水及带出的有害气体等次要隐蔽致灾因素,并提出了相应的预防和治理措施。

Research of the hidden disaster factors in Hongshiyan coal mine

In order to ensure the safety of coal mining and formulate prevention and control measures,the hidden disaster factors of Hongshiyan mine were researched.According to the exposed geological conditions,the existing results of drilling,geophysical exploration and water quality test,and the gas grade identification data,combined with the characteristics of concealment,time-varying,sudden,difficult detection and prevention of hidden disaster causing factors,the hidden disaster causing factors in Hongshiyan coal mine were analyzed.The results show that the gob water around the main and auxiliary shafts,the water conducting fracture zone caused by mining are the main hidden disaster factors,the activation and lag of fault water and harmful gas are the secondary hidden disaster factors,and the corresponding prevention and control measures are put forward.
