摘 要: 以國內(nèi)外深部資源開采現(xiàn)狀及其研究成果為基礎，綜述國內(nèi)外工業(yè)界和學術(shù)界對深部的劃分和界定，探討深部界定的標準、深地資源的極限采深及其開采模式；同時對提升運輸方式如何適用深部開采的要求、深井開采高溫如何調(diào)節(jié)等進行歸納總結(jié)，并提出一些新的構(gòu)思；特別是針對深部稀有、貴重、戰(zhàn)略資源的開采理論與關(guān)鍵技術(shù)，結(jié)合深部硬巖礦山高應力、高井深和高地溫等特點，給出“變害為利”的新策略和初步研究結(jié)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.
Key words: deep mining; critical depth; deep mining method; deep hoist and transportation; deep filling and cooling technology; convert harm into benefit
