摘要
通过对新三矿瓦斯含量、瓦斯涌出量观测数据值进行定量、定性分析,得出瓦斯赋存分布规律。对实际绝对瓦斯涌出量、瓦斯含量与统计的相应煤层底板标高进行线性回归分析,对瓦斯涌出量进行了预测。研究结果显示,新三矿瓦斯赋存具有随煤层埋深增大而增大的规律,其特征较为明显;由断裂、褶曲、水文地质条件、顶底板岩性等构造因素引起的瓦斯赋存规律不甚明显。
Based on quantitative and qualitative analysis of the gas content and emission in Xinsan Mine,the distribution of gas occurrence was obtained. The linear regression analysis was carried out on the absolute gas emission rate, content and floor level of relevant coal seam, and the absolute gas emission rate and content were predicted. The results showed that the gas content increased with buried depth obviously, it was not very related with fracture, fold, hydrogeological conditions and the roof and floor lithologic.
