摘要
为配合开磷集团做大做强的目标要求,用沙坝矿生产能力要提高到200万t/a,需多个中段同时开采才能实现。同时开采2~5个中段,需要充填采矿区,以控制矿区的沉降量。通过有限元计算,并对计算结果进行了稳定性分析,达到了提高矿区开采安全性,实现多中段安全开采的目的。
To meet the target of Kailin Group Yongshaba mine should reachs 2 million t/a, which to be bigger and stronger, production capacity of could be realized with multiple middle pieces mining together. Filling mining area is needed to control settlement of mining area when 2 - 5 middle pieces min-ing together. Through finite element calculation, and stability analysis was done on calculation results, aim of improve extraction security in mining area and realize multiple middle pieces safe mining was reached.
