| 摘 要： | 多数情况下,胶结充填矿山的充填体经常承受着邻区开采大爆破产生的重复冲击荷载的作用。本文从胶结充填体的材料构成特点出发,运用微小单元下的波动能量理论,对在应力波作用下的充填体能流变化情况及其动力响应规律进行了分析,提出了胶结充填体动力强度的一般准则。

| Abstract: | Consolidated filling body in a cemented filling mining system often suffers periodical and nonperiodical shock loading ection from massive blasting operations in adjacent areas. Considering the composition of the filling material the author discusses the changes in energy flow under stress wave action and the dynamic response rules using wave energy theory of mini-element. A preliminary criterion is proposed for dynamic strength of consolidated filling body. |
