过断层石门揭煤突出危险性预测方法的探索

Exploration of Forecast of Cross-cut Coal Uncovering Outburst Danger Through Fault

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。

Analysis the forecast of cross-cut coal uncovering outburst danger through fault in a coal mine in Henan,for the inaccuracy of pressure measurement through fault and the uncertainty influence of the outburst by the fault, In order to provide reference to determine coal outburst danger through fault, put forward the method of analysising the property of fault by measuring the relationship between the gas pressure and the linear distance to fault, Ensure absolute safety of cross-cut coal uncovering, judgement by selecting the parameter of coal on both sides of the fault in favor of outburst when using the comprehensive index of D,K to predict the dangerous of outburst, predict the dangerous of the cross-cut coal uncovering successful.
