摘要
赣南某钨矿东部低品位矿体受采矿生产能力和经济效益影响一直未得到有效开采,同时在中西部高品位矿体采动塌陷影响下安全开采难度大。研究提出上行式大直径深孔阶段空场嗣后充填高效采矿技术与工艺,采场综合生产能力350~380t/d,采矿直接成本约30元/t,安全经济地实现了低品位难采东部钨矿体的高效开采。
The eastern lean difficult-excavated ore body of a tungsten mine in Southern Jiangxi was not mined because of economic benefit and mining production capacity. In the influence of the mining subsidence caused by mining the central and western rich ore body, the eastern ore body is more difficult to excavate. Long-hole sublevel open stoping with backfilling mining method and technology is put forward to mine the eastern lean difficult- excavated tungsten ore body safely, economically and efficiently.
