为了研究煤层瓦斯含量与煤层埋藏深度之间的关系,以对高瓦斯及突出矿井进行瓦斯含量的准确预测,利用理论推导与现场试验结合的方法对煤层瓦斯含量与煤层埋藏深度之间的定量关系进行了分析。分析结果表明,随着煤层埋藏深度的增加,瓦斯含量不断增加;现场试验结果显示,在瓦斯风化带以下,随着煤层埋藏深度的增加,瓦斯含量呈上升趋势;但随煤层埋藏深度的不断增加,瓦斯含量的增加速度却不断减小,到达一定的煤层埋深后,瓦斯含量趋近于某一固定值。由此可得出,煤层埋藏深度在一定范围内,煤层瓦斯含量与煤层埋藏深度呈正比关系,但随着埋藏深度的增加,正比例系数逐渐减少,瓦斯含量基本保持不变。
In order to study the relationship between the gas content in coal seam and the depth of coal seam burial, and to accurately predict the gas content in high gas and protruding coal mines, the quantitative relationship between the gas content in coal seam and the depth of coal seam burial Analyzed. The results show that the gas content increases with the increase of burial depth of coal seam. The field test results show that the gas content increases with the increase of burial depth of coal seam below the gas weathering zone. However, with the continuous increase of burial depth , The rate of increase of gas content has been decreasing. After reaching a certain depth of coal seam, the gas content approaches a certain fixed value. It can be concluded that the depth of coal seam burial is within a certain range, and the gas content of coal seam is directly proportional to the depth of coal seam burial. However, with the increase of burial depth, the proportional coefficient decreases and the gas content remains basically unchanged.
