凡口矿深部废石回填系统的建立及应用效果分析

On the Application Effect of Deep Barren Rock Backfill System in Fankou Lead- zinc Mine

凡口铅锌矿针对井下采准区域掘进废石与回采区域空区回填所需废石区域分布不协调的问题,在现有采准工程基础上,建立和完善了深部废石回填系统,解决了掘进废石转运、堆放问题,确保废石最大限度回填到采空区。

Aiming at the distribution discordance problem between the tunnelling barren rock of underground stope preparation area and backfill required barren rock of recovery area dead zone, Fankou lead - zinc mine established and perfected deep barren rock backfill system under the basis of the prsent stope preparation project. It worked out the problems of tunnelling barren rock transfer and ensured the barren rock backfilled to goaf with the highest limit.
