以某矿1304孤岛工作面具体条件为研究基础,对孤岛工作面顶板破断规律及动压致灾机理进行研究。通过理论分析与公式推导,得到顶板最大拉应力、最大弯矩值及释放弹性能的大小,不仅提供了顶板最大拉应力、最大弯矩及释放弹性能的计算方法,而且为研究顶板破断规律及减少冲击灾害提供依据。
Based on the specific conditions of the 1304 island working face of a mine, the roof breaking principle and the mechanism of dynamic pressure and pressure disaster are studied. Through the theoretical analysis and formula derivation, the maximum tensile stress, the maximum bending moment and the release elastic energy are obtained, which not only provide the calculation method of the maximum tensile stress, the maximum bending moment and the release elastic energy of the roof, Reduce the impact of disasters provide the basis.
