摘要:为准确预测煤层的煤与瓦斯突出危险性,在对瓦斯含量预测煤与瓦斯突出理论分析的基础上,系统
介绍了瓦斯含量直接测定工艺,并对 7433 工作面煤层瓦斯含量进行了测定,通过瓦斯涌出量和瓦斯压力对
瓦斯含量的反算结果对瓦斯含量测定结果的准确性进行了检验,进而对 7433 工作面的煤与瓦斯突出危险性
进行了预测。研究结果表明:瓦斯含量决定了煤体内部积聚的瓦斯内能,是反映煤与瓦斯突出危险性的重
要因素,一定的瓦斯含量是突出发生的必要条件;瓦斯含量的准确测定是瓦斯含量法预测煤与瓦斯突出的
基础,该瓦斯含量直接测定工艺可准确测定煤层瓦斯含量,其中瓦斯损失量的准确确定是关键;经测定 7433
工作面的煤层瓦斯含量为 ~ m3/t,综合工作面的地质构造和其他预测指标判定 7433 工作面为无
突出危险区。

Abstract: To accurately predict coal and gas outburst hazard of coal seam, based on the theoretical
analysis of outburst danger prediction by gas content, the direct measurement technique of gas content
was systematically introduced and gas content of 7433 working face was determined. The accuracy of
determination result was tested by inverse calculation of gas content through gas emiss
