中文摘要: 彝良驰宏矿业有限公司Ⅰ号矿体846中段839分段楼板矿大约有1.5万t高品位矿石,70 %的原生矿,30 %的伏槽矿。矿块高度约13 m,有很高的经济价值。近年来由于安全威胁及采矿难度特别大,此块矿石一直未得到回采。直到人工砼胶结充填法的诞生,此块矿才得以安全回采,取得了很好的经济效益。
Abstract:There were 15 thousand tons of high grade ore in sublevel 839 of middle section 846 of ore body Ⅰ in Yiliang Chihong Mining Industry Company, 70% of them were primaryore, and 30% of them are fu-cao ore body. The ore body with high economic value is 13 meters in height,which can’t be mined because of the risk threat. Until it emerged cemented backfill mining method, the ore body is mined safely.
