对西山矿区瓦斯地质规律的分析

在分析西山煤田地质勘探与煤矿生产中收集的瓦斯地质资料的基础上,对西山矿区的瓦斯赋存规律进行了研究。总结出相对涌出量随开采深度增大而增大,埋藏越深的煤层一般来说其瓦斯压力、瓦斯含量与相对涌出量越高,瓦斯赋存主要受向斜构造的控制、褶曲构造的控制作用等瓦斯地质规律。并就开采顺序对瓦斯涌出量的影响,采煤工作面瓦斯涌出量分析、预测与初步评价进行了事例总结。阐述了瓦斯涌出量预测的内容,如采面瓦斯相对涌出量采后鉴定、利用瓦斯赋存规律研究结果之公式对采面瓦斯相对涌出量进行预测,进而结合每月平均日产量计算采面瓦斯绝对涌出量等。

Analysis on Gas Geological Rule in Xishan Mining Area

On the basis of analyzing the geological exploration of Xishan coal field and the gas geological data of collecting in coal production,studies gas occurrence law of Xishan.Sums up the gas geological laws such as with mining depth increasing relative emission increasing,in general the gas pressure,gas content and relatively emission of buried deeper seams is higher,gas occurrence is controlled mainly by syncline structure,control effect of folded structure and so on.And carry out summary on the impact of min...
