针对煤与瓦斯突出影响因素众多、防治难度较大的问题,分析了寺河井田的区域构造背景,总结了寺河煤矿煤与瓦斯突出特征和日常预测指标变化规律,研究了煤层瓦斯、煤体结构、应力分布和地质构造等因素与煤与瓦斯突出之间的关系,确定了寺河煤矿煤与瓦斯突出的主要控制因素为煤层瓦斯和地质构造,并据此提出了严格控制煤层瓦斯、加强地质构造探测、多角度综合预报突出危险和规范防突管理4个方面的防突对策,为寺河煤矿煤与瓦斯突出防治提供给了指导。

According to many factors affected to the coal and gas outburst and the high difficult prevention of the coal and gas outburst, the paper analyzed the regi onal structure background of Sihe Minefield, summarized the features of the coal and gas outburst occurred in Sihe Mine and the variation law of the routine predicted i ndexes and studied the relationship between the seam gas, seam structure, stress distribution, geological structure factors and coal and gas outburst. The paper deter mined that the major control factors of the coal and gas outburst in Sihe Mine were the seam gas and geological structures. Based on those factors, there were four out burst prevention and control countermeasures to seriously control the seam gas, to enhance the exploration of the geological structures, to comprehensively predict the outburst dangers from different angles and to standardize the outburst prevention management were provided, which provide the guide for the coal and gas outburst pre vention and control in Sihe Mine.
