摘要
金川二矿区是我国唯一一座年产矿石突破350万t的大型镍矿产资源生产基地,其开采工程已经进入到850中段,开采深度超过千米,随着开采深度加深,矿区地压、地热、涌水等显现日趋剧烈,并潜在着突变失稳的风险。因此,深部高效、安全和低耗开采是金川矿区乃至金属矿山亟待解决的重要课题。本文结合金川二矿区目前开采现状和遇到的问题,探讨分析了深部开采面临的技术问题,并提出了研究对策,对深部矿山资源开采具有一定借鉴。
The Jinchuan No. 2 mining area is the only large - scale production base of nickel mineral resources in China with annual ore production being over 3,500,000t/a, mining operation down to -850 level, and the exploiting depth exceeding one kilometer. As the exploiting depth extends, the mining area geopressure, geothermal power, water welling- up, etc. appear and become gradually violent, besides, it has the potential risk of sudden changes and loss of stability. Therefore, high - efficiency, safety and low consumption deep exploiting are important subjects for Jinchuan mining area and other metal mines to expect earnest solution. By com- bining the Jinehuan No. 2 mining area＇s current mining situation and problems facing at present, this paper discusses and analyzes technological problems existing in deep mining , and putd forward some research countermeasures, which can be are used as reference for deep- buried resources mining.
