荥巩煤田西段二_1煤层瓦斯赋存规律研究

Studying the gas distribution rule of Xing gong coalfield west-middle section Ⅱ1 seam

研究煤层瓦斯赋存规律,对于煤与瓦斯突出区域预测和防治具有重要指导意义。本文以瓦斯地质理论为指导,大量测试了煤层瓦斯含量参数,分析了荥巩煤田西段二1煤层的瓦斯赋存规律,找出了瓦斯赋存的控制因素。研究结果表明,煤层埋藏深度、地质构造、煤层厚度是控制荥巩煤田西段二1煤层瓦斯赋存的主要因素。

Studying the gas distribution rule for the coal anti gas outburst regional prediction and prevention has important instruction signifi- cance. Based on gas geological theory, a large number of test the seam gas content were done, Xing gong coalfield west-middle section Ⅱ 1 seam gas distribution rule was analyzed, the control factors for gas distribution was found. The research resuhs show that depth of coal seam, geological structures, coal thickness are the important factors for gas distribution for Xing gong coalfield west-middle section Ⅱ 1 seam.
