摘要
综合分析了砂岩与油气突出是地应力、油气压力及岩石物理力学性质等因素综合作用的结果;并介绍了海石湾矿风井岩芯法及其突出预兆法预测突出危险的试验情况。
The compre hensive analysis showed that the burst of sandstone and oil gas was re sulted in the combined action of the factors such as strata stress,oil gas pressure and the physico-mechan-ical properties of rock.This paper gives a descrip tion of the use of core method and outburst omen method to predict outburst hazard in airshaft of Haishi wan Coal Mine.
