西曲矿12314工作面蹬空开采可行性分析

Feasibility Study on Mining above Hollow at 12314 Working Face in Xiqu Colliery

以西曲矿2号煤层12314工作面蹬空开采为实际工程背景,综合运用比值分析法、“三带”理论分析法、围岩平衡分析法和经验公式分析法等四种分析方法,对其蹬空开采的可行性进行分析研究,并对蹬空开采区域可能遇到的情况提出建议,以保证12314工作面蹬空开采的安全可靠性,对该矿其他类似条件下的蹬空开采工作面的可行性分析具有一定的借鉴意义。

Based on the actual engineering background of No.2 coal seam at 12314 working face in Xiqu Colliery,the paper studies on the feasibility of mining above hollow by four analysis method——ratio analysis method,“Three Zones”theory analysis method,surrounding rock equilibrium analysis method and empirical formula analysis method,and presents suggestions for handling possible situations in mining above hollow area,which can ensure the mining safety and reliability and provide a reference for the feasibility analysis of mining above hollow in other mines with similar conditions.
