崩落矿岩的移动规律,国内外许多学者进行了长期的大量的研究,并取得了许多突破性的研究成果.但是,由于放矿过程是一个动力学过程.放矿时松散矿岩以动载荷作用于放矿场边界,在回采过程中。放矿场的边壁和底部经受着这种载荷的反复作用。导致采场底部结构,采场侧壁,包括相邻矿块的巷道和未采矿体等的垮落和滑动等破坏。本文在分析放矿过程中矿岩移动规律的基础上.提出了放矿流动体和固结体概念。应用数学弹性理论。采用带椭圆孔无限体和半平面体的变形叠加方法,获得了放矿场固结体.特别是放矿场边界压力基本解,以及其动态响应。
Many studies have been carried out by many scholars at home and abroad, and many breakthrough research results have been obtained.Because the ore-discharging process is a dynamic process, when loose ore is loosened with dynamic load Role in the mine boundary, in the process of mining. The side walls and bottom of the mine are subjected to repeated loads of this type. Resulting in the collapse of the bottom structure of the stope, the sidewalls of the stope, the roadway including the adjacent ore blocks and the non-mining bodies, and the like. Based on the analysis of ore movement in the process of ore drawing, the paper put forward the concept of ore body and consolidation body for ore discharge. Applied mathematical elasticity theory. The deformation superposition method with infinite body and semi-flat body with oval holes was used to obtain the consolidation of the ore body, especially the basic pressure of the boundary conditions of the working face and its dynamic response.
