摘　　要：柿竹园有色金属矿在分段凿岩阶段矿房采矿法的实践中,针对过去漏斗受矿、双电耙道出矿底部结构之不足,成功试用了一种V形堑沟受矿、双电耙道出矿的底部结构,获得了较好的效果,对该矿采矿工艺的完善及类似矿山的开采具有实用价值,本文详细介绍和分析了这种底部结构的特点.According to the shortcomings of bottom structure which uses cones for ore reception and dual scraping drifts for ore removal originally, We made a successful use of bottom structure wich uses V-gully for ore reception and dual-scraping drifts for ore re-moval in practising the sublevel drilling and level room mining method in shizhuyuan Non-ferrous Metals Mine, and obtained a better result. This bottom structure, of which characteristics are described and analyzed in detail in this paper, is of practical value to the improvement of mining technology used in this mine and to the mining of similar mines.
