摘　　要：采用现场采样、实验室测试和理论分析相结合的方式,研究建立某矿区3#煤层原始煤体瓦斯含量与瓦斯压力之间的关系,定量确定该矿区3#煤层瓦斯压力0.74MPa对应的瓦斯含量及区域预测瓦斯含量指标临界值。In order to study the relationship between reservoir pressure and gas content, this paper finds out the functional relation between original gas content and reservoir pressure in 3^# coal seam of some mine area, through theoretical analysis based on the data gotten from mine and laboratory test, and it＇s calculated for gas content when reservoir pressure is 0.74MPa and the critical value of coal and gas outburst prediction index about original gas content in 3^# coal seam.

关 键 词：煤层 瓦斯含量 瓦斯压力 临界值
