摘　　要：煤层瓦斯(煤层气)含量测试结果是矿井瓦斯灾害综合防治和煤层气资源开发利用的重要基础数据,针对目前测试规范不统一,测试结果差异较大,不具有可比性的问题,严重影响了煤层原始或残余瓦斯含气量的准确判断。通过统计综合分析的方法,对现有的测试规范进行归纳和对比,结果表明:依据现有测试规范,瓦斯(煤层气)含量测试结果并不能够反映实际值的大小,测试结果具有相对性,采用定点取样等复杂测试方法逼近其“真值”的做法意义不大,测试的重点在于提高测试方法的便利性和测试结果的可比性,为修改完善现有测试规范、开发智能化测试仪实现瓦斯含量大量快速测试和有效利用奠定基础。The test results of coal seam gas(coalbed methane)content are the important basic data for the comprehensive prevention and control of mine gas disasters and the development and utilization of coal seam gas resources,the problem of non-comparability seriously affects the accurate judgement of original or residual gas content in coal seam.Through the method of statistical comprehensive analysis,this paper sums up and compares the existing test specifications,and the results show that according to the existing test specifications,the test results of gas(coalbed methane)content can not reflect the actual value,it is of little significance to approach the"true value"of the test results by using some complicated test methods such as fixed-point sampling,the key point of the test is to improve the convenience of the test methods and the comparability of the test results,it lays a foundation for modifying and perfecting the existing test specifications and developing intelligent test instrument to realize a large amount of rapid test and effective utilization of gas content.
