摘 要: 針對(duì)傳統(tǒng)緩傾斜多層礦體的采礦方法,如全面法、 中深孔落礦下盤漏斗法和爆力運(yùn)搬法等, 生產(chǎn)能力小、 勞動(dòng)強(qiáng)度大、 安全性差、 成本高等缺點(diǎn), 從云南錫業(yè)公司松樹腳錫礦“大馬蘆”礦段的實(shí)際開采技術(shù)條件出發(fā), 提出了一種新型頗有特色的緩傾斜多層礦體的采礦方法——深孔合采井下礦廢分離連續(xù)采礦法。 它采用大直徑深孔合采礦巖、井下礦巖集中分離、 連續(xù)采礦等技術(shù), 變革了傳統(tǒng)的分采工藝, 有效地克服了傳統(tǒng)采礦方法的弊端, 為緩傾斜多層礦體的高效、 低耗和安全開采提供了新的技術(shù)方案。

Abstract:The traditional mining methods for extraction of the slightly inclined, multi-layers deposits, such as overall mining, bottom-chuting with medium-length holes and ore overthrowing mining by blasting, have low productivities, high labor intensity and costs, and/or poor safety. A new mining method——continuous mixing mining applied underground ore-waste separating, was put forward for this kind of deposit. An application of it was made to Da Malu deposit in Songshujiao Tin Mine of Yunnan Tin Corporation according to the mining conditions there. By the method, the ore and rock all together are first blasted, then separated underground. The mining process can be conducted continuously. The method is a new mining technique possessing high efficiency, low material consume and high safety for the mining of this kind of deposit.
