STUDY ON THE HIGH EFFICIENT MINING SCHEME OF INCLINED FRACTURED OREBODY IN HOUHEMUSHAN IRON MINE

Abstract

Abstract

According to the geological characteristics, testing results of granule flow parameters and the point-load strength of No 1 ore-body in Houhemushan iron mine, the rule of ore-rock falling and granule flowing are investigated and utilized. A high efficient scheme of sublevel caving without sill pillars is put forward, which adopts the induced falling techniques and footwall drifts and combined ore-drawing modes. The method has been put into operation, and better-applied effect is obtained now.
