摘要/Abstract

摘要： 针对无底柱分段崩落法损失存在的贫化问题，分别阐述了放矿随机介质理论、放矿连续介质理论和爆破优化的研究发展过程，包括散体移动概率密度方程、偏心率方程、爆破优化实用模型等，从整体角度研究回采过程，分析放矿中的放出体和松动体，及落矿中崩落体的量化关系，建立三者量化循环模型，对矿石开采进行控制和预测，以减少井下矿石的损失贫化。

关键词: 放矿理论, 爆破优化, 崩落体, 损失贫化

Abstract: In view of the loss and depletion of sublevel caving without sill pillar,the development process of the ore drawing stochastic medium theory ,ore drawing continuous medium theory and optimization of blasting are discussed respectively,which include bulk movement probability density equation,eccentricity equation,the utility model of blasting optimization and so on.Then quantification relationship of drawn out body and loss body of the ore drawing and the collapse body of the caving ore are analyzed in detail,and the quantitative circle model of them is established so as to control and predict the ore exploration and reduce the ore loss and depletion.

Key words: Drawing theory, Blast optimization, Caved ore body, Loss and depletion
