水平分层充填采矿法采场接顶充填方案探讨

Discussion on Stope Roof Contact Backfilling Schemes of Horizontal Layer Cut and Fill Stoping method

针对上向水平分层充填采矿法采场回采结束后充填接顶困难导致的片帮、局部冒顶等地压活动,利用ANSYS有限元软件对接顶方案进行数值模拟分析、筛选,并提出了切实可行的接顶措施,为下一步矿房回采提供了安全保障,也为深部地压显现规律及控制技术的研究和管理提供了理论依据。

Aiming at the ground pressure activities like rib spalling,local caving and so on which caused by roof-contacted filling difficult after stope mining finished of horizontal cut and fill stoping,numerical simulation analysis is done on roof-contacted scheme by using ANSYS finite element software.Feasible roof-contacted measure is selected and proposed,and it provides safety guarantee for the next stoping of room,and theoretical basis for research on behavior regularity and control technology of deep ground pressure and ground pressure management.
