在收集整理黄岩汇煤矿地质资料和瓦斯资料的基础上,运用地质构造控制理论,展开井下实测和地质编录,以分析矿区和井田地质构造分布特征,研究地质构造、顶底板岩性、煤层埋藏深度等地质因素对瓦斯赋存的影响,得出了井田内15号煤层瓦斯含量分布规律和构造煤的分布规律;同时,对黄岩汇煤矿15号煤层突出危险性也进行了区域预测.研究表明,煤层埋藏深度是影响黄岩汇煤矿15号煤层瓦斯含量分布的主控因素,其他地质因素仅仅影响煤层瓦斯的局部变化;将埋深大于321m的15号煤层划分为突出危险区,其余的则为非突出危险区.
Based on control theory of geological construction, the actual measurement and geological logging are developed, the occurrence regularity of geologic construction is analyzed, the influence factors of gas occurrence, such as the geologic structure, the rock character of roof and floor, the burial depth of coal-bed, hydrogeology conditions and so on are researched, by collecting the geologic and gas data systematically. The gas content distribution law and the distribution of tectonic coal are revealed, and the outburst danger of No. 15 coal seam in Huangyanhui mine is predicted. The research shows that: the burial depth of a coal-bed is the main control factor that affect the gas content distribution of No. 15 coal seam in Huangyanhui coal mine, and other geological factors affect the local variation of coal seam gas; the buried depth being greater than 321m for No. 15 coal seam .is divided into an outburst dangerous area, and the rest is a non-outburst danger district.
