为解决平煤股份十矿己15－24100机巷石门揭煤难题,根据井下煤层赋存地质条件,在己15－24100机巷向采面方向5 m 处施工一条66 m 揭煤辅助巷,巷道位于己15煤层顶板以上7 m,向下施工穿层预抽钻孔,辅助巷的施工提高了钻孔施工的精度、扩大了钻孔的覆盖范围,结合己15－24100机巷钻孔,在机巷掘进头和平硐石门辅助揭煤巷同时施工抽采钻孔,消除煤层的突出危险性。
為解決平煤股份十礦己15－24100機巷石門揭煤難題,根據井下煤層賦存地質條件,在己15－24100機巷嚮採麵方嚮5 m 處施工一條66 m 揭煤輔助巷,巷道位于己15煤層頂闆以上7 m,嚮下施工穿層預抽鑽孔,輔助巷的施工提高瞭鑽孔施工的精度、擴大瞭鑽孔的覆蓋範圍,結閤己15－24100機巷鑽孔,在機巷掘進頭和平硐石門輔助揭煤巷同時施工抽採鑽孔,消除煤層的突齣危險性。

To solve the difficult problem of coal exposed through crosscut in the F1 5 G24100 intake roadway of the 10 th Coal Mine of Pingdingshan coal industry Co??,Ltd??,according to the geological conditions of coal seams occurrence,the auxiliary coal exposed roadway which was 66 m long and located in 7 m above the roof of F1 5 coal seam and the down pre drainage boreholes through coal and rock seams were drilled in was constructed at 5 m away from the F1 5 G24100 inG take roadway directing the working face?? The construction of auxiliary coal exposed roadway imG proved the accuracy of the boreholes drilling and expanded the coverage of boreholes drilling?? The outburst danger was eliminated by drainage boreholes which located in roadway and driving face of the F1 5 G24100 intake roadway and auxiliary coal exposed roadway through horizontal crosscut.
