【摘要】 矿井瓦斯赋存分布规律研究涉及瓦斯风化带的确定和影响煤层瓦斯赋存的主控地质因素两个方面.结合司马煤矿煤层瓦斯情况,运用地质构造控制逐级制理论分析了矿井的瓦斯赋存特征,确定了3号煤层的瓦斯风化带、瓦斯的赋存形式及影响煤层瓦斯赋存的地质因素,揭示了3号煤层瓦斯聚集规律,分析了矿井瓦斯突出危险性指标,运用单项指标法对3号煤层煤与瓦斯突出危险区进行预测,为合理开发利用煤层瓦斯,防治煤与瓦斯突出和今后的安全生产提供了科学依据.更多还原

【Abstract】 The determation of gas weathering zone and the main control factors of the gas occurrence are the two aspects of the discussion of the rule of gas occurrence in coal mine.This artical introduces the basic conditions of the Sima coal mine which including analyz the gas consequences in Sima coal mine and using the theroy of sequential control system of geological structure to analyze the features of the gas occurrence in coal.Thus it defines the gas waethering zone in No.3 coal mine and analyzes the occurrence of gas and the main effective geology factors of gas occurrence.In order to exploit the gas of coal reasonably,prevent and cure the coal and gas outburst,provide the foundation for the safe production in the future,this article aims to analyze the danger index of gas outburst and predict the danger zone of coal and gas outburst in No.3 coal mine by using the single index method.更多还原
