　　采场内结构体的存在对矿块安全回采影响较大，开展其解算方法与稳定性计算方法研究具有重要意义。应用一般块体理论，以采场四周的开拓巷道结构面调查数据为基础，运用GeneralBlock程序初步解算出采场内结构体，分析结构体的真实性，制定真实性分级表。结合3DMine软件，用定义包裹长方体的方法准确刻划结构体的位置，建立简单材料力学模型，计算出固定结构体的最小固定面面积。对于解算出的结构体，在块体可移动性定理和稳定性原理的基础上，运用材料力学、集合等方法，分析矿块回采过程中结构体可移动性，计算结构体稳定性系数。研究成果成功解算出采场内结构体并进行了稳定性分析，对于裂隙岩体加固与采矿工艺优化具有较好的指导意义。

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.
