对河南某矿过断层石门揭煤的突出危险性进行分析,针对穿断层测压的不准确性与断层对突出影响的不确定性,提出了通过测定瓦斯压力与距断层距离之间的线性关系来分析断层性质的方法,为判断断层2侧煤体的突出危险性提供参考依据;使用D、K综合指标进行突出危险性预测时,选取断层2侧煤体较为有利于突出的参数进行判定,确保石门揭煤的绝对安全,成功预测了该石门揭煤的突出危险性。
Based on the analysis of the outstanding risk of coal exposure to a crosscutting crosscut in a mine in Henan Province, aiming at the inaccuracy of fault penetrating fault and the indefinite influence of faults on the outburst, To provide a reference for judging the outburst danger of coal body on the 2 sides of the fault; when using D and K comprehensive indexes to predict the outburst danger, it is more advantageous to judge the prominent parameters by selecting 2 coal bodies on the fault side, To ensure the absolute safety of the stone door uncovering coal successfully predicted the outstanding danger of exposing the stone door.
