乌兰矿采矿现状及技术应对方案

Mining situation analysis and technical solution in Wulan Mine

本文分析了乌兰矿投产前期采矿现状及存在的主要问题,针对该矿所处蒙古国经济落后、投资风险大的现实状况,为避免生产中断、规避投资风险,早日回收前期投资考虑,采取了双斜坡道开拓、全尾胶结充填、高端壁空场嗣后充填采矿、多中段组合式连续开采等系列技术应对方案。通过本方案大大降低了一次性投资规模及投资风险,前期投资得以快速回笼的同时,矿山产能充分释放,确保了矿山的持续稳定,取得了较好的经济效益和社会效益,为海外地下近地表矿体开采矿山规避投资风险提供了很好的技术方案借鉴。

This paper analyzs the present mining technology situation and the main problems in Wulan Mine,based on the actual investment environment such as poor economy,huge investment risk in Mongolia,a series of technical solution such as double-ramp transport,full-tailing cemented filling,high-end open-stope subsequent filling mining method,multiple level combination continuous mining are put into use aiming to avoid production disruption.Through this scheme investment risk aversion,quick recovery of investment.Which greatly reduced the one-time construction investment and potential risk.With previous investment got quickly recovered,meanwhile the productivity fully released,sustainable development and economic benefit,social benefit achieved.Valuable reference are provided to the near-surface ore body mining plan and oversea investment aversion in this paper.
