【摘要】 根据矿区大地构造位置、构造演化和区域构造应力场的特点,总结和分析了铁厂沟煤矿构造特征及其对煤层瓦斯的控制作用,确定了瓦斯含量与煤层埋深的正相关关系,提出了煤层埋深是铁厂沟煤矿煤层瓦斯赋存的区域主控因素,压性或压扭性断裂附近是瓦斯灾害局部防治的重点,对铁厂沟煤矿以及具有相似地质条件的煤矿瓦斯治理工作具有指导意义.更多还原

【Abstract】 Based on study of tectonic location,tectonic evolution and regional tectonic stress field,the paper summarizes and analyzes the geological struchure characteristics and the control on coal bed methane(CBM),confirms the positive correlation relationship between the gas content and buried depth of coal seam in Tiechanggou coal mine.The main control factors of CBM have been demonstrated in the coal mine.The research lays the foundations of gas control project in Tiechanggou coal mine and gives the reference for others with similar geological conditions.更多还原
