摘    要:以国内外深部资源开采现状及其研究成果为基础,综述国内外工业界和学术界对深部的划分和界定,探讨深部界定的标准、深地资源的极限采深及其开采模式;同时对提升运输方式如何适用深部开采的要求、深井开采高温如何调节等进行归纳总结,并提出一些新的构思;特别是针对深部稀有、贵重、战略资源的开采理论与关键技术,结合深部硬岩矿山高应力、高井深和高地温等特点,给出“变害为利”的新策略和初步研究结果。

Abstract: Based on the current situation of deep resources exploitation at home and abroad and its research achievements, the division and difference of the deep from industry and academy around the world were summarized in this work. The definition and the critical depth of deep mining for solid mineral resources and its mining modes were also discussed. Then, some new strategies and/or alternatives on deep mining for solid mineral resources were proposed for deep hoist & transportation, and temperature control of deep mining, etc.. Lastly, incorporating with the characteristics of high stress, great lifting depth and high temperature in deep hard-rock mines, a new strategy and mining mode which can be “convert harm into benefit” were given for the deep rare, valuable and strategic resources exploitation.
