黔金矿煤层瓦斯赋存规律及突出危险性预测

Gas Occurrence Regularity and Gas Outburst Risk Prediction of Coal Seam in Qianjin Mine

通过对贵州黔金矿井9号煤层瓦斯含量、压力、瓦斯涌出量等数据测定和统计,分析了影响9号煤层瓦斯赋存的地质因素,得到瓦斯赋存及分布规律。并对9号煤层的突出危险性进行了预测,对指导矿井瓦斯灾害治理具有重要意义。

Based on the data measurement and statistics of gas content,pressure, gas emission of the 9th coal seam in Qianjin Coal Mine in Guizhou Province, geological factors which impact the methane occurrence of the 9th coal seam were analysed, the occurrence and distribution laws of gas were figured out, gas outburst risk of the 9th coal seam was also forecasted. It has important practical significance to guide the gas control of coal mine targetedly.
