缓倾斜极薄矿体回采,一直是一个高难度的科研课题,不少贫薄矿山亦为之棘手。湖南省桃江锰矿缓倾斜极薄碳酸锰矿床表现尤为突出:倾角<38℃,矿体平均厚度仅为0.4m。由于削壁量大,矿岩不能下放,采场不得不采用人工运搬的方法。劳动强度大,工作效率低。为解决这一问题,桃江锰矿技术部门和生产工区联合攻关,进行“缓倾斜极薄矿体采矿方法探索试验”。经过一年的试验研究表明:缓倾斜极薄矿体采用分段、
Gently inclined very thin ore body mining, has been a difficult scientific research topics, many thin mines are also tricky. In Hunan Province, the Taocheng manganese deposit is characterized by its gentle sloping ultra-thin carbonate manganese deposit with an inclination of <38 ℃ and an average thickness of 0.4m. Due to the large amount of wall, ore can not be decentralized, stope had to use manual transport method. Labor intensity, low work efficiency. In order to solve this problem, Taojiang manganese ore technology department and production area jointly tackled the issue of “the exploration and test of the gently inclined thin and extremely thin orebody mining method”. After a year of experimental studies have shown that: gently inclined very thin ore body using segmented,
