摘 要: 针对传统缓倾斜多层矿体的采矿方法,如全面法、 中深孔落矿下盘漏斗法和爆力运搬法等, 生产能力小、 劳动强度大、 安全性差、 成本高等缺点, 从云南锡业公司松树脚锡矿“大马芦”矿段的实际开采技术条件出发, 提出了一种新型颇有特色的缓倾斜多层矿体的采矿方法——深孔合采井下矿废分离连续采矿法。 它采用大直径深孔合采矿岩、井下矿岩集中分离、 连续采矿等技术, 变革了传统的分采工艺, 有效地克服了传统采矿方法的弊端, 为缓倾斜多层矿体的高效、 低耗和安全开采提供了新的技术方案。

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.

 

Key words: slightly inclined ore body; multi-layered deposit; ore-waste separation; continuous mining tec
