摘要
为创造良好的安全回撤条件,鄂庄煤矿在瓦斯异常区回撤工作面实施切顶卸压和补强支护收尾技术,将支架前后顶板分成两个独立块段,弱化顶板压力传递关系,强化架前支护,解决了回撤通道顶板支护技术难题,为安全、高效回撤夯实了基础。
In order to create good conditions for safe withdrawal,Ezhuang Coal Mine implemented roof cutting pressure relief and reinforcement support wind up technology at the withdrawal working face in the gas abnormal area,divided the front and rear roof of the support into two independent blocks,weakened the transitive relation of roof pressure,strengthened the support in front of the rack,solved the technical problem of roof support for the withdrawal channel,and laid a solid foundation for safe and efficient withdrawal.
