摘　　要：针对端氏煤矿3107回采工作面倾向长度大,单侧施工检验钻孔易发生飘移,检验结果可靠性差的难题,理论分析与现场考察结果表明,在工作面单侧施工检验钻孔比两侧施工检测钻孔的残余瓦斯含量测值降低9.71%,倾向长度大的工作面进行预抽效果检验时应采取两侧顺槽布孔方式。开采过程中测试的区域验证指标未出现超标现象,瓦斯涌出亦未出现异常现象,验证了两侧布孔的方式,其检验结果具有较好的可靠性。In the light of the problem that the inclination length of 3107 working face in Duanshi coal mine was large, single side constructed detecting drill-holes were prone to deviating, test results were poor reliability. Theoretical analysis and field survey results show that the measurement of the residual gas content in the working face with single side of the drill-holes was 9.71% lower than that of the both sides, working faces which have large inclined length should be taken in way of both side holes when carried on pre-drainage effect test. Tested index of regional verification did not exceed the standard when was working, and yet there was no abnormal phenomenon of gas emission, it checked results of testing that both sides constructed drill-holes was of preferable reliability.
