摘　　要：以贵州桐梓县容光煤矿11202工作面区域防突措施效果检验数据为基础,分析在较小范围内测定大量瓦斯含量参数的情况下,使用部分煤样残存瓦斯量及灰分数据来计算其他煤样瓦斯含量的计算结果与实测值的偏差情况,并分析其产生的主要原因。有针对性的提出统一煤样粒度和井下测定煤样重量的改进措施。通过现场实验证明改进措施有效地减少计算结果与实测值之间的差别,使计算结果更接近真实值。The research is based on the data measured in effect test of regional anti-outburst measures at 11202 coal mining face of Rongguang Coal Mine. The residual gas content and ash content of some coal samples were used to calculate the deviation between the calculated results and the measured values of gas content from other coal samples, and the main reasons of its occurrence are analyzed. The improvement measures of unified coal sample size and determination of underground coal sample weight are proposed. Through field experiments, it is proved that the improvement measures can effectively reduce the difference between the calculated result and the measured value and make the calculated result closer to the real value.
