摘要
工作面回采过高冲击危险区时,常规的爆破卸压方法不能有效解危,必须根据现场条件合理改变爆破参数及施工技术,可以降低冲击危险,能有效地避免冲击地压灾害发生。
The impact of excessive extraction face the danger area,bursting relieving the conventional methods can not effectively Jiewei,must be based on reasonable conditions to change the scene blasting parameters and construction technology can reduce the risk of impact,can effectively avoid the impact of disasters and pressure.
