【摘要】 本文试图通过有限元数值计算,研究鸡笼山金矿南缘采场用充填法采矿时,不同的施工方法对采场稳定性的影响,要考虑的因素有:单个采场较好的开挖、充填顺序;较为理想的充填材料的弹性模量;较为有利的矿房及矿柱的宽度;多个采场共存时施工顺序的优化。从中找出最佳的施工方案。更多还原

【Abstract】 In this paper,the authors try to study the effects of the different construction methods on the stope stability if the filling mining is used in the south stope of Jilongshan gold mine with the FEM.The factors considered are:the better excavation and filling orders of single stope,the more ideal modulus of the filling materials, the more favorable widthes of the rooms and pillars,the optimization of the construction sequences when there exist several stopes.Finally,the best constrction scheme is founded.更多还原
