摘要
以实测的皇联煤业3煤层瓦斯基础数据为基础,分析了控制煤层瓦斯赋存的地质因素,得到了煤层的瓦斯赋存规律,为瓦斯防治工作提供重要依据。煤层埋深是影响3号煤层瓦斯赋存的主控因素。3煤层瓦斯含量增长梯度为0.0068m3/(t·m),瓦斯压力增长梯度为0.0004MPa/m,3号煤层最大瓦斯含量为5.97m3/t,最大瓦斯压力为0.194MPa。
Based on the measured data of 3 coal seam gas in HuangLian Coal Industry, the geological factors controlling gas occurrence in coal seam are analyzed, and the law of gas occurrence in coal seam is obtained, which is an important basis for gas prevention and control work. The buried depth of coal seam is the main controlling factor affecting gas occurrence in No. 3 coal seam. 3 coal seam gas content growth gradient is 0.0068m^3/ （t·m）, the gas pressure growth gradient is 0.0004MPa/m, the maximum gas content of No. 3 seam is 5.97m^3/t, and the maximum gas pressure is 0.194MPa.
