中文摘要：

为准确预测矿井深部煤层瓦斯含量,分析了煤层埋藏深度、基岩厚度和地温对煤层孔隙率和瓦斯含量的影响,得到了影响瓦斯含量的主控因素。研究结果表明：瓦斯含量随基岩深度的增加逐渐增高,每百米增加3.73m3/t.r,瓦斯含量随温度的升高逐渐降低,温度每升高1℃,煤样吸附瓦斯量就减少0.29m3/t.r。

英文摘要：

In order to accurately predict gas content in deep seam coal mining,the influence of the coal seam depth,bedrock thickness,temperature of stratum and gas content have been analyzed in this study.The main factors influencing gas content were obtained.The results showed that with an increase in bedrock depth the gas content increases gradually.Results from the study showed that gas concentrations increased by approximately 3.73 m3/t·r for every hundred metres of depth however,gas content reduced gradually with the increase of temperature.A temperature rise of 1℃ resulted of a reduction of 0.29 m3/t·r in coal gas samples.
