摘　　要：嘉禾县袁家矿区浦溪井属高沼气矿井，自1986年投产以来，共发生煤与瓦斯突出70多次。其中大部分发生在褶曲轴部和断层附近，其次是煤层厚度变化处。对浦溪矿区的地质资料和煤与瓦斯突出资料详细研究后表明：控制该矿区煤与瓦斯突出的地质因素有地质构造、煤层厚度及其变化和围岩特征等，其中地质构造是影响煤与瓦斯突出的决定因素。该成果对进一步研究矿井瓦斯的赋存和涌出规律及其类似矿井的生产，具有重要的指导意义。Puxi mine field contains rich marsh gas, more than 70 times coal and gas outbursts have been taken place in the Puxi mine field since 1986.The most were taken place in the fold axis and fault. Detailed studies show that the coal and gas outburst is connect with the geological structures. Thickness of coalbed, the changing of coalbed and character of surrounding rock. The geological structures is the main facter. The results have an important sense to investigating coalbed gas preservation and emission law and the mining of coalbed to similar mines.
