利用钻屑解吸法测定煤层瓦斯压力的应用

Determinating methane pressure in coal seam application with the method of desorption of drill-cuttings

本文在实验的基础上,根据煤屑瓦斯解吸规律,测定了煤钻屑解吸指标同煤层瓦斯压力的关系,进而确定了红岭煤矿的煤层瓦斯压力。经实际考察,确定的煤层瓦斯压力值可作为评价煤层瓦斯含量和煤层突出危险性鉴定的参考值。

This paper determinates the relationship between desorption index of drill - cuttings and the methane pressure in coal seam, which is based on a set of experiments and the rule of desorption of drill-cuttings, then the methane pressure in coal seam of Hong Ling coal mine has been determined. It proves that the value of the methane pressure in coal seam could be used as the reference value to assess of the methane content of the coal seam and determinate the hazard of the coal and methane outburst.
