摘要: 中厚倾斜矿体在进行崩落法卸压开采时,需要根据卸压效果来布置采场结构及参数。分析了影响中厚矿体崩落法卸压开采的因素,确定了卸压开采与矿体条件、采场结构参数、回采参数以及崩落矿岩性质间的相互影响关系,并建立了卸压开采与影响因素间的动态约束条件。通过上述研究,为中厚矿体崩落法卸压开采的参数选择和优化提供了相应的依据和方法。

Abstract: When the medium-thick ore-body is mined by depressurized mining method, the stope structure and the parameters should be chosen and arranged according to the depressurized effect. So, the influence factors of depressurized mining on medium-thick ore-body are analyzed. As a result, the influencing relationship of the depressurized mining with the ore body condition, the stope design parameters, the mining parameters and the blasted ore drawing characteristic are determined. Then the dynamic constraint condition is established. Based on the research above, it provides a basis and proposal for the choice and optimization of parameters for depressurized mining of the medium-thick ore-body.

Key words: Medium-thick ore-body, Depressurized mining, Influencing factor, Dynamic constraint
