一、概述 抚顺西露天矿目前正处于技术改造阶段,开拓工艺由原单斗电铲,铁道运输系统、逐步过渡到铁道、卡车、固定破碎机、皮带运输机提升,分区开采,联合运输半连续开采工艺。初期集中开采地质条件较好的西部采区(E1000以西),后期利用西部采空区作为内部排土场。1989年煤炭产量由技术改造前的250万吨/年,过渡到500万吨/年,富矿由700万吨/年,过渡到1000万吨/年。 实现上述技术改造工程的关键是如何在 I. Overview Fushun West surface mine is currently undergoing technological transformation stage, pioneering the process from the original single-bucket electric shovel, railway transportation system, and gradually transition to railways, trucks, fixed crusher, belt conveyor upgrade, zoning mining, combined transport semi-continuous mining process . In the initial stage, the western mining area with good geological conditions (west of E1000) will be exploited in a concentrated manner and the western goaf will be used as an internal drainage area in the later period. In 1989, the output of coal shifted from 2.5 million tons / year prior to technological transformation to 5 million tons / year and that of rich ore increased from 7 million tons / year to 10 million tons / year. The key to achieving the above technical renovation project is how
