摘要:

露井协调开采顺序关系到两种开采方式之间相互制约和影响的程度,结合平朔矿区露井协采工程实践,设计先井工后露天开采和先露天后井工开采两套方案进行数值模拟,对比分析了不同露井协调开采顺序下露采边坡变形破坏特征。根据分析结果,从维护边坡平整和稳定的角度,建议在露井协采生产实践中采用先井工后露天的开采模式,且露天开采进度滞后于井采活跃期。

Abstract:

Coordinated open-pit with underground mining order is related to the degree of its restrict and influence between two different mining system. Under the background of coordinated open-pit with underground mining engineering practice in PingShuo mining area. The characteristics of slope deformation destruction of open-pit coal mine in different coordinated open-pit with underground mining order was analysed by numerical simulation. According to the results of the analysis, the mining model of open-pit mining lagging behind underground mining was suggested in coordinated open-pit with underground mining practice based on the point of keep slope level and stability, and open-pit mining progress should lagging behind underground mining active period.

Key words: coordinated open-pit with underground mining, mining order, slope deformation destruction, underground mining disturbance
