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。
Aiming at the disadvantages of the traditional gently inclined multi-layered orebody mining methods, such as the comprehensive method, the mid-deep hole mining under the tray funnel method and the explosive force transport method, the production capacity is small, the labor intensity is high, the safety is poor and the cost is high. Based on the actual mining conditions of the “Damalu” ore section of the tin company Songshuoduxi, a new type of gently inclined multi-layered orebody mining method Continuous mining method. It adopts the technology of large diameter deep hole co-mining rock, underground ore concentrate separation and continuous mining and changes the traditional sub-mining technology to effectively overcome the shortcomings of the traditional mining methods. Consumption and safe mining provides a new technical solution.
