高压水力压裂技术在渝阳煤矿石门揭煤中的试验应用

Experimental Study on High Hydraulic Fracturing Technology in Rock Cross-cut Coal Uncovering Yu Yang Coal Mine

本文通过对N3704中部2撑上山M8煤层石门揭煤点进行高压水力压裂，然后与N3702中部2撑上山M8煤层石门揭煤点进行比较，平均单孔抽采浓度提高了29％～52．8％，管道抽采纯量提高了3倍左右；并在渝阳煤矿应用以后，取得良好的应用效果。

Based on the N3704 middle 2# mountain M8 Cross-cut Exposing Coal Seam points to beat the high-pressure water and the N2702 middle 2# mountain M8 Cross-cut Exposing Coal Seam points comparison,The average drainage hole concentration increased 29.2%-52.8%;Pipe drainage volume increases 3 times. Hydraulic fracturing technology corssing coalbed drilling application achieved good results ofYu Yang coal mine.
