摘要
先房后柱的上向分层胶结充填法在我国应用较为广泛,但矿柱后期回采条件较差。连续采矿法具有独特优越之处,但其全面拉开后采场的稳定性有待验证。本文从喀矿地质条件出发,用岩石力学观点和有限元模型对两种方法进行比较、分析和选择,为采矿方法综合决策提供了力学方面的论证。
The practice cf mining room first and then pillars by overhand cut and cemented fill is widely used in China, but the condition for pillars recovery in later period is normally worse. Therefore, continuous mining method is possessed of unique merits, yet the stability of stope after full opening waits to be proved. From the geologic conditions in Kalatongke Mine, the paper has made analysis, comparison and selection between both the above methods and provided grounds on rock mechanics for mining method selection.
