【摘要】 随机介质理论可以很好地反映崩落法放矿的矿岩移动规律。它可以解决各种边界条件下的放矿问题。本文着重讨论了随机介质理论在端部放矿中的应用。利用参数辨识方法求出了反映散体性质的介质参数。从而可以判断无底柱分段崩落法矿块结构参数是否合理?为设计合理的结构参数提供了依据。更多还原

【Abstract】 The stochastic medium theory of ore-drawing can properly reflect the movements of ore and rock masses for caving system. It can solve ore-drawing problems with various boundary conditions. The applications of the stochastic medium theory in the face-end ore-drawing are discussed in this paper. Medium parameters reflecting the loose body properties are determined by using the parameter recognition method. Thus the rationality of the ore-block structure parameters of pillarless sublevel caving system can be identified and the rational structure parameters of design can be provided.更多还原
