摘　　要：缓倾斜中厚矿体的回采普遍存在采场矿石运搬效率低,高大空场的顶板管理困难和作业安全问题以及采矿强度低等突出问题,因而属世界采矿难题。试验集成了先进的振动助流技术、爆力运搬技术,并采用新型的振动助流器与大功率电耙配套,“V”型集矿堑沟底部结构,用1条电耙道取代3条电耙道。创造了329t/d的采场生产能力,较矿山同期用的底盘漏斗采矿法提高了65%。采场直接经济效益达234万元。为我国地下矿这类难采矿体的回采创造了一种新型高效低耗安全的采矿法。Low ore haulage efficiency, difficult roof management of high and large mined area, operation security question and poor mining intensity that are projecting problems commonly existing in the extraction of gently inclined medium-thick orebody are challenges of world mining. The researh integrated advanced vibrating flow-aiding technology and explosive force haulage techniques and used the combination of new vibrating flow-aiding device with high-powered electric rake, “V” type bottom-structured ore gathering trench and a drag scraper path which replaced three traditional ones, creating a 325 t/d stoping capacity, 65% higher than that of bottom-chute mining that was then used at the mine, and a direct economic benefit of 2.34 million yuan. A new type highly effective low-cost safe mining method was thus created for underground mining of such hard-to-mine orebodies in China.
