摘要
针对富家矿30m中段57m水平矿体变窄,储量减少,原下向倾斜六角形高进路分层胶结充填采矿法开采矿石贫化率、采矿损失率增大等问题,改用下向高分层机械化胶结充填采矿法,通过转层、进路合并、高架金属(木)棚子支护等创新技术的应用,取得了显著的应用效果。创新技术值得推广。
The orebody of 57m level in 30m midsection became narrow and the reserve decreased. With the former downward inclined hexagon high route delamination cemented filling mining method, the ore dilution rate and mining loss factor increased obviously. With downward high delamination mechanized cemented filling mining method, and some innovation techniques, such as delamination transfer, route mergence and metal or wood structure supporting, ideal results were achieved.
