摘　　要：针对深井厚大矿体,往往优先选用大直径深孔空场嗣后充填法进行开采,但如何进一步减少采切比、提高盘区生产能力一直是我们面临的主要技术难题。本文以思山岭铁矿大规模开采为例,探究采场大段高回采的技术经济可行性,对120 m大段高和60 m段高进行详细技术经济对比,推荐思山岭铁矿首采-1 020 m中段依然采用60 m段高进行开采。Large-diameter deep-hole open stoping with subsequent backfilling method is often preferred for mining deep and thick deposits, but how to further reduce cutting-mining ratio and improve panel production capacity remains the main technical challenge we face. Taking as an example the large-scale mining in Sishanling Iron Ore Mine, this paper explored the techno-economic feasibility of large lift stoping. Detailed techno-economic comparison was made between 120 m lift and 60 m lift. As a conclusion, 60 m lift was still proposed for the-1 020 m starter level of Sishanling.
