测定瓦斯含量取样方式存在问题分析及解决对策

Problem Analysis and Solutions About Sampling Way of Gas Content Determination

瓦斯含量测定结果的准确性对于煤矿开采,评估煤层气储量起着至关重要的作用,本文重点对井下直接测定瓦斯含量常见取样方式进行总结。通过分析井下实际生产中常用的直接测定瓦斯含量的取样方式,找出采用该对应取样方式对煤层瓦斯含量测定结果影响的主要因素,并通过对主要影响因素的综合考虑,试图找到一种更可靠,更简便,测定结果更加准确的测定瓦斯含量的取样方法。

The accuracy of gas content determination results plays an important role for coal mining and the evaluation of coal seam methane reserves.The common sampling ways are described mainly to measure gas content directly in underground coal mine.Through the analysis for common sampling ways of direct gas content determination in actual underground production,these main influence factors are found out about the corresponding sampling ways for coal seam gas content measurement results.Based on the comprehensive consideration of main influence factors,the sampling way of gas content determination is tried to find,it is more reliable,more simple,and its determination result is more accurate.
