矿井煤与瓦斯突出地质因素分析及防治

Geological Factor Analysis of Coal and Gas Outburst and Prevention Measures

煤与瓦斯突出是受多种因素影响的突发性复杂瓦斯动力现象,其中瓦斯地质是影响煤与瓦斯突出的重要因素。从矿井地质概况着手分析了煤与瓦斯突出的特征和一般规律,并据此分析了煤与瓦斯突出的地质因素,提出煤层赋存变化、开采深度、地质构造和顶板水是矿井煤与瓦斯突出的主要因素。根据矿井实际提出了煤与瓦斯突出预防性措施。

Coal and gas outburst is an sudden and complicated gas dynamic phenomena influenced by many factors especially the gas geology. By analysis of the characteristics and regularity of coal and gas outburst from the geologic aspects, the author points out the main geological factors of coal and gas outburst--such as the change of coal seam occurrence, mining depth, geological structure and roof water, and proposes the preventive measures according to the actual mine conditions.
