本文将介绍菲勒克斯采矿公司在目前开采水平(1020m水平)上应用强制崩落法开采矿块的情况。这种强制崩落法采用大孔径(165mm)潜孔凿岩爆破方式。本文介绍了其采准布置,各种井巷的掘进顺序,与常规拉底循环有关的凿岩、装药及爆破,实施该方案所发生的费用以及潜孔强制崩落方法的效果。 This article will introduce the case of Felix mining company mining by forced caving at the current mining level (1020m). This forced avalanche method uses a large aperture (165mm) DTH borehole blasting. In this paper, the author introduces the layout of mining and mining, the sequence of tunneling, the drilling, charging and blasting related to the conventional bottoming cycle, the cost of implementing the scheme and the effect of the forced hole-down method.
