摘　　要：从煤层瓦斯含量与瓦斯压力、地质构造与地应力、煤层结构特征及地下水作用等影响煤与瓦斯喷出动力现象的地质因素着手,利用采掘活动导致断层活化及顶板离层原理,分析一起探压钻孔间歇性煤与瓦斯喷出动力现象机理,并提出了预防措施。This paper commencing from the geologic agents of the gas bearing capacity and the pressure of gas in the coal bed, the geological structure and the geostress, the structural feature of the coal bed and the function of the underground water and so on which effect the blowout dynamical force phenomena of coal and gas, analyses the mechanism of a phenomena of intermittent blowout dynamical force of coal and gas resulting from the explored press drilling by using the principle of excavation causing the activation fault and the abscission layer of crest, and points out preventive measure.
