放矿制度

缓倾斜中厚矿体放矿制度的研究

A research on ore-drawing order of a dip at slow angle and middle thickness orebody

有底柱阶段崩落法底部结构及放矿制度优化

Law of orebody caving by block caving system optimization of bottom structure and drawing regime in block caving with bottom pillars

利用离散元中刚性块体模型，模拟了多种放矿制度下，覆盖岩层与矿石的相互作用及移动过程，反映了矿岩的流动特点和接触线变化过程。

The DEM ( discrete element method ) model of rigidity block was used to simulate the interaction and movement between the overburden and the ore in several ore drawing systems , which could reflect the flow characteristics and the change in contact line between the ore and the overburden .

阶段崩落法放矿中侧面崩落岩石混入量和放矿制度间的关系

Relations between mixing volume of flank caved rock and system of ore drawing

本文通过对崩落矿块的随机模拟放矿和物理模拟放矿说明，侧面岩石混入量与放矿制度有关，并从数量上给出了这种关系。

By means of both random and physical simulation of ore drawing , this paper expounds that the mixing volume of flank caved rock is concerned with the ore drawing system , and gives the quantitative relationship as well .
