梧桐庄井田瓦斯地质规律研究

Study on Gas Geological Law of Wutongzhuang Mining Area

煤层瓦斯赋存规律研究是瓦斯灾害防治的基础。介绍了峰峰矿区和梧桐庄井田的地质构造特征,采用瓦斯地质分析的方法,分析了梧桐庄井田的瓦斯赋存规律。研究表明:梧桐庄井田地质构造的发育受到矿区和区域构造的逐级控制;局部瓦斯赋存异常主要受到断层和褶曲地质构造分布的影响;煤层瓦斯含量随着埋深的增加而增大;煤层埋藏深度和地质构造是控制梧桐庄井田瓦斯赋存的主要因素。

The gas distributed rule of coal seam is the basis of gas disaster prevention. The geological structure characteristics of Feng- feng mining area and Wutongzhuang Coal Mine were introduced. By using the method of gas geology analysis,the gas occurrence regularity in mine field of Wutongzhuang Coal Mine was analyzed. Research shows that,geological structural development is controlled step by step by mining area and regional tectonic, and local gas occurrence is influenced mainly by the distribution of the geological structure of faults and folds, coal seam gas content increases with depth. Buried depth of coal seams and geological structure are the main factors controlling the gas occurrence of Wutongzhnang Coal Mine.
