兰尖铁矿十余年来的生产实践证明,山坡露天矿采用平硐溜井开拓运输系统,在技术上、经济上都是最合理的。 本文介绍了我矿多年应用中总结出的一套有效措施及其使用管理经验,做到新水平准备,采场推进时选择时机劈开降段,保证多台阶能同时卸矿,并实现汽车水平运输。 The production practice of Lanjian Iron Ore over the past ten years proves that it is technically and economically most reasonable to use the openhole slipway to open up the transportation system. This paper introduces a set of effective measures and management experience of mine which have been summed up for many years in our mine, so as to prepare for a new level, to select the timing to split the descending stage when the stope is advanced, to ensure that multiple steps can be simultaneously unloaded and to realize the automobile level transport.
