| 摘 要： | 矿体在开采结束后,其采空区顶板会在高应力状态下积聚大量的弹性能,并在一定的条件下突然释放,形成冲击灾害。建立了采空区顶板大面积垮落时冲击气浪最大气流速度和破坏载荷预测理论模式,大大简化了冲击灾害发生时的理论分析、推导过程,为防灾工程提供了科学、简便的设计依据,对矿山安全生产和灾害预防具有重要意义。

| Abstract: | After ore being mined,a great deal of elastic energy shall accumulate in the roof of the mined-out areas under high stress,and may suddenly release under certain conditions,cause impact hazard.A theoretical model for forecasting the maximum air speed of blast and destroy load occurring when roof of mined-out area collapses in large area was established,this can greatly simplify the theoretical analysis of impact hazard,and provide scientific and simple design basis for hazard prevention projects,is of great... |
