摘要
基于煤矿井下长距离密闭取芯工艺测定瓦斯含量技术尚无标准的现状,为保证该技术测定结果的可靠性,需利用已知技术同该工艺测定的结果进行比较,以此对其可靠性进行验证。为此,探讨了三种可行的验证方法:在同一水平面与常规方法测出的结果直接进行比较;与区域瓦斯含量统计计算结果相比较;在采样点下部的巷道中施工并借助穿层钻孔采用常规方法在相同区域采集煤样进行瓦斯含量测定,测出结果后与之进行比较。结合在煤矿井下实际应用的情况,分析了三种验证方法各自的利弊,以此为长距离钻孔密闭取芯工艺测定瓦斯含量结果的可靠性提供参考依据。
Based on the present situation that there is no standard for measuring gas content by long-distance closed coring technology in underground coal mines,in order to ensure the reliability of the measurement results of this technology,it is necessary to use the known technology to compare with the measurement results of this technology,so as to verify its reliability.Therefore,this paper discussed three feasible verification methods:one is that the results measured by the same horizontal plane and the conventional method are directly compared;the second is to compare with the statistical calculation results of regional gas content;and the third is to carry out construction in the lower roadway of the sampling point and take conventional methods with the help of cross layer drilling to take coal samples in the same area for gas content determination,and then compare with the measured results.Combined with the actual application in the coal mine,the advantages and disadvantages of the three verification methods were analyzed,so as to provide reference for the reliability of the results of gas content determination by long-distance borehole closed coring process.
