摘　　要：根据某铁矿矿区难采破碎矿体—第四系条件下急倾斜厚大矿体的具体特点以及矿山生产现状,对其进行采矿方法研究,提出了几种适合此类矿体开采的采矿方法,经比较优选出适用于该矿体开采条件的分步后退式大直径深孔阶段空场嗣后充填采矿法,为国内其他类似开采技术条件的矿体提供借鉴。According to the specific characteristics of the thick orebody with steep dip angle of quaternary system and the present production status, the mining method for one troublesome and broken iron orebody is studied in this paper. On the basis of the comparison of several suitable mining methods for this kind of orebody, the paper recommends the backward block stoping and subsequent filling method that is mined step by step with large-diameter longhole, which can provide references for other orebody with the similar mining technical conditions.
