摘要
中厚矿体采用崩落法卸压开采时,不但需要考虑卸压效果,还应考虑开采取得的技术经济指标。分析了卸压开采的影响因素,并根据卸压开采采场结构布置形式建立了废石混入率与各参数间的关系,依据开采所能允许的技术经济指标确定了中厚矿体卸压开采的适用条件。探讨了主要采场参数对开采技术经济指标的影响。通过上述分析,为中厚矿体卸压开采技术适用条件的确定以及卸压开采参数优化提供了可行方法。
When the medium-thick ore-body is mined by depressurized mining method,it is not only to consider the depressurized effect,but to consider its mining technical and economic index.The influence factors of depressurized mining are analyzed,and the relationship between mining parameters and waste rock mixed rate is established according to the stope structure layout of depressurized mining.Then the applicable condition for medium-thick ore-body depressurized mining is ensured based on the permitted technical and economic index of mining,and the influence of stope structure parameters on technical and economic target is discussed.Based on the research above,a reliable way for determination of applicable condition for depressurized mining of medium-thick ore-body and the parameters optimization of the depressurized mining is provided.
