摘要
把地下矿山因开采而形成的大型采空区改建为尾矿库,是处理采空区的有效方法。在把采空区改建为尾矿库前,需要对空区围岩进行稳定可靠性评价。但空区围岩稳定可靠性评价不能采用普通结构的模型。本文分别从围岩系统和围岩地表环境出发,对它的建模方法进行了探讨。
It is a useful approach to construct tailing ore bin hy a large gob area which is fomed due to mining. It is necessary to evaluate the stability of surounding rocks of gob area be fore it is constructed as tailing ore bin. But when evaluating the stahility of surrounding rocks of large gob area, we can't adopt a model which is applied to evaluate stability for a general structure. The paper explores a modeling method for eva1uating the stability of surrounding rocks of large gob area according to surrounding rock system and grourld surface environment of surrounding rocks respectively.
