中文摘要：

快速实现原位取样是准确测定煤层瓦斯含量的基础,为研究不同取样方式对瓦斯含量测定的影响,以淮南潘二煤矿11223工作面为例,对比深孔定点取样与孔口接粉取样方式下取样效果,并对采取的煤样利用直接法进行瓦斯含量测定对比分析。结果表明：深孔定点取样装置满足现场取样要求,且采用深孔定点方式取样可提高瓦斯含量测定准确性。

英文摘要：

As you know,quickly achieving situ sampling is the base of accurate determination of gas content.In this paper,to study the influences of different sampling modes on the determination of gas content,working face 11223 of 3coal seam in Paner Mine in Anhui province is taken as an example,orifice mode and fixedpoint sampling mode are inspected and the gas content values are analyzed by direct gas determination method.The results show that the fixed-point sampling device can satisfy site sampling requirements and improve the accuracy of determination for coal gas content.
