苏联矿山倾斜(25°~55°)矿体很多。在克里沃罗格铁矿区,占总可采面积的70%的矿体,倾角为42°~55°,厚度为30~60m。克里沃罗格铁矿区开采这类矿体应用最广泛的采矿方法是采场内重力运搬矿石的分段矿房法和分段崩落法。由于矿体的倾角限制沿矿体倾斜自流运搬的使用范围,采用这些采矿方法势必要准备大量的分段。
Soviet Union mines tilt (25 ° ~ 55 °) a lot of ore body. In the Krivolugar iron ore district, 70% of the total recoverable area of the ore body, dip angle of 42 ° ~ 55 °, the thickness of 30 ~ 60m. The most widely used mining method for mining such ore bodies in the Krivoy Rogo iron ore mine is the staged mine approach and the sub-caving method of gravimetric transport of ore in the stope. Due to the inclination of the ore bodies which limits the scope of use of the inclined gravity transport along the ore body, it is necessary to prepare a large number of sections using these mining methods.
