摘要
为在岩孔壁上刻出两条对称槽线 ,以在外力的作用下发生“应力集中” ,以实现岩石定向断裂 ,研究并制造出了风动潜孔式刻槽机。介绍了风动潜孔刻槽机的工作原理、槽线参数和机械特征 ,及其在石材矿山的应用情况及发展前景。
Two symmetric trough lines must be grooved on the rock wall to realize a diretional rupture according to the stress concentration, and so a pneumatic down-the-hole groover was developed and manufactured. The principle of operation, trough-line parameters and mechanical characteristics are introduced. Its application in stone mines is introduced.
