草楼铁矿充填接顶新工艺

New Roof-Contacted Filling Technics in Caolou Iron Mine

采空区接顶充填效果对充填采矿法矿山的安全和生产都有较大影响,草楼铁矿根据该矿具体情况总结出了一套新的接顶工艺,虽然工序较传统的略有增加,但其接顶率很高,在实际生产中取得了很好的效果,为该矿后继的采充作业提供了强有力的技术保障,同时也可为类似矿山的接顶充填提供参考。

Roof-contacted filling of mined-out area has considerable influence on safety and production of mine in witch filling mining method is used.In Caolou Iron Mine,a new roof-contacted filling technics was developed according to the concrete conditions.This technics have a slight increasing working procedure contrast to conventional technics,but the rate of roof-contacted can be very increased,resulting in good effect in practical production.It provide a strong technical support for the later mining and filling in the mine and a reference to similar mine.
