Synchronous filling mining technology idea and a kind of representative mining method

Under the guidance of two ideas that are non-waste mining and synergistic mining which differ from the traditional synchronous filling,when the space of gap has not been released,making partial space of gap act as transformation space in advance and explanting the filling technology to the front part of ore drawing process so that they can be simultaneously implemented,the "synchronous filling" mining technology idea is creatively derived.Based on the guidance of synchronous filling idea,through absorbing the advantages of filling mining technology so as to secondly innovate the mining process of short-hole shrinkage stoping method,a new method of "ore drawing largely,synchronous filling and non-top-pillar shrinkage stoping method" was put forward.This new mining method can prevent the surrounding rock from dropping,control the ore dilution ratio and loss rate,improve the ore recovery rate,restrict the surface subsidence.Meanwhile,this new method not only provides an opportunity for the regular pattern of ore drawing under the action of isolated layer but also promotes the new development of ore drawing theory.
