摘要
济宁三号煤矿排矸系统主要以胶带输送机为主,随着矿井的开拓延深,排矸运输线路不断加长,运输环节不断增加,排矸费用随之加大。本文主要介绍了在采区边界三角煤区域采用掘进采煤,矸石充填已掘煤巷的技术,经济效益非常显著。
Jining NO.3coal mine use belt conveyor as main waste stone exhaust system,with the extension of coal mine,waste stone exhaust route become longer and longer,and the cost become bigger and bigger.This thesis mainly introduce the mining technology of coal mining boundary triangle area and the gangue backfilling technology,which bring favorable economic benefit.
