充填假顶破裂处理方法的应用

Application of the stowing mat breaks treatment technique

胶结充填采矿方法为提高矿石回采率和提高现场标准化、持续矿石回采工作提供安全的条件,在矿山得到越来越广泛的应用。随着矿石回采速度逐步提高,现场安全出现了很多问题。针对金川矿区下向六角形进路倾斜式胶结充填采矿方法的充填顶板加固及充填顶板破裂问题进行研究,在实际应用中取得了较好的效果。

The consolidated fill stoping provides the safety conditions for improving the ore recovery rate and the field work standardization,as well as the continuous stoping, and it has been used more and more widely. The fastening of the ore stoping production brings some problems to the field safety. The filled roof reinforcement and the roof breaks problems in using inclined consolidated fill stoping with downward hexagon drift in Jinchuan mining area were studied, and it achieved good results in practical application.
