Study on rockmass moving predicting method due to combined excavation of mines

摘要：

In the course of mining,there are many mines in which a situation of combined underground and open pit exists.Depending on the relation among spatial positions of stopes,the influencing realms due to different mining excavation are overlapping.It would result in the interaction and superimposition of two types of mining effect.A system of dynamic state superimposition should be constituted.Thus,the deformation mechanism of slope rock mass becomes more complicated and differs from that caused exclusively by open pit mining.However,in the conventional method of slope stability,this kind of influence is usually ignored.Its effect may be different from that of real situation.Therefore,based on professional theoretical analysis this paper tries to explore the deformation mechanism of slope rock for composite system combined underground and open pit mining.The relevant evaluating method is concluded subsequently.
