摘　　要：瓦斯含量是瓦斯防治的基础依据,取样是现场含量测定的关键。在大湾煤矿西井X11101工作面进行了定点取样研究,采用深孔定点取样装置取样和孔口接粉2种方式进行取样,分别测定瓦斯含量并进行了对比分析。考察了深孔定点取样技术在大湾煤矿取样的适用性。结果表明:深孔定点取样技术可实现定点、快速取样,取样深度已达到87 m,取样时间控制在5 min以内。利用深孔定点取样技术取样进行含量测定可有效提高煤层瓦斯含量测定的准确性。Coal gas content is the basis of gas disaster prevention and control,sampling technology is the key factor in the determination process of gas content the sampling fixed-point sampling experiment was researched on the working face of X11101 coal seam in Dawan mine west well.By the analysis of the determination results of gas content between orifice and fixed-point sampling,the applicability of fixed-point sampling technique has been studied in in Dawan mine.The results have shown that the sampling could be fixed-point and rapid the sampling depth was up to 87 meters and the time was less than 5 minutes.The application of fixed-point sampling technology could be better to prevent and control gas disasters by improving the accuracy of determination for the coal gas content.
