【摘要】 通过试验测试不同岩性岩体以不同位势能下落冲击岩石基座振动速度的变化,并探讨了影响振动能大小的因素;基于实验室测定位势能转化为振动能转化规律,提出了矿震能量的定量确定思路。实验表明:不同性质岩石冲击碰撞过程中,转化为振动能的多少与岩石性质相关,且随岩石下落高度增大,转化为振动能的比例逐步降低。本研究对塌落振动研究也具有一定的借鉴意义。更多还原

【Abstract】 Based on the analysis of the transformation between static energy and the power that created from the rock mass rushed floor of mined-out area,the effect on energy of vibration,broken and deformation of dash was analyzed.By analyzing experiment result,we have draw a conclusion that the conversion of vibration energy,in course of shocking and impacting rock of various propertie,relates to rock properties,increases with the height of rock falling,and the conversion ratio to vibration energy decreases gradually.The research result is also useful to studying falling vibration.更多还原
