Solution of structure body and its stability calculation in stope
摘要
Abstract
For the existence of stope structure body having a great influence on the safety mining of ore block, it is very important to carry out the method for calculating the structure body and its stability. By the application of general block theory, based on the data of structure plane in the developing roadways surrounding the stope, structure bodies in stope were preliminarily worked out by using GeneralBlock code. The authenticity of structure body was analyzed; and its grading table was established. Combined with 3DMine software, the structure body positions were accurately marked by defining the package cuboids. A material mechanics model was established; the minimum area of the fixed structure plane in the fixed structure body was gotten. For the calculated structure body, according to the block mobility theorem and stability theory, using methods of material mechanics and sets, the mobility of structure body during the ore stoping process was analyzed; and the coefficient of structure body stability was obtained. The results for calculating the structure body and its stability provide a good guide for strengthening and optimizing the mining technology of the fractured rock mass.关键词
