摘要
Abstract
Ore drawing in stope is a difficult problem when the inchned orebody is extracted.The mining technology that sublevel open stoping method by using of trackless mining equipment for ore drawing is proposed according to the specific circumstances of the underground stoping of Malu phosphate ore,and the stope bottom structure design is improved by the footwall rock of sublevel caving,in order to guarantee the ore can be passed through the bottom with the ore self weight.This mining practices was done in mine,the results show by using this method can reduce the loss and dilution,improve the mining intensity and stoping efficiency and reduce the mining cost,which has the better promotional value and economic benefit.关键词
