露天-井下联合开采矿井边界参数确定及优化

Determination and optimization of boundary parameters of open-pit and underground combined mining

露天-井工联合开采(露井联采)会造成露天与井工两种开采模式的相互干扰,影响主要发生在露天与井工矿的边界处。本文通过对露井联采矿井边界类型的合理区分,分析了不同边界条件下两种开采模式相互干扰的主要形式以及干扰导致的主要破坏模式,针对不同类型的边界提出了不同的参数优化方法。

The mutual interference of open-pit mining mode and underground mining mode in open-pit and underground combined mine occurs mainly in the boundary of the two mining modes.Based on the reasonable distinction between different boundary conditions of the two mining mode, analyzed the main forms of mutual interference and the main failure mode caused by the interference under diffe-rent boundary conditions,proposed different parameters optimization methods in view of different boundary conditions.
