中文摘要：
详细介绍煤岩体内的储能及其变化,提出了煤岩体发生冲击矿压的能量条件,并从储能和应力的关系出发对冲击破坏发生的力学模型进行了分析,最后简要提出降低煤岩体内储能可减弱冲击危险.
英文摘要：
The paper introduced the accumulated energy and variation in the rock mass. The paper provided the energy conditions of the rock mass to have bumping pressure. The paper analyzed the mechanics model failed with the humping from the relation of the accumulated energy and stress. The paper pointed that to reduce the accumulated energy may reduce the risk of the bumping.
