Method for reducing underground impact of mine slope landslide
The invention provides a method for reducing underground impact of mine slope landslide, which comprises the following steps of: laying a lower ore sand layer in a full-coverage manner by taking a pit bottom area of an open-pit mine as a bottom surface; a pile group shock insulation layer is laid on the lower ore sand layer; an upper ore sand layer is laid on the pile group shock insulation layer; and a slope toe broken stone hardcore is arranged at the slope toe of the side slope where the potential landslide mass is located. Through relative sliding among the pile groups in the pile group shock insulation layer and the damping effect of the pile groups, the ore sand layer and the slope toe broken stone hardcore, the landslide impact force direction is changed, most of impact is converted into horizontal transmission from downward transmission, and the impact range is converted to the opposite side slope toe from a top plate area of a mining area.
本发明提供一种降低矿山边帮滑坡对井下冲击的方法，包括以露天矿坑底区域为底面，全覆盖地铺设下部矿砂层；在所述下部矿砂层的上铺设桩群隔震层；在所述桩群隔震层上铺设上部矿砂层；在潜在滑坡体所在的边帮坡脚布设坡脚碎石垫层。本发明通过桩群隔震层内部桩群之间的相对滑动，及桩群与矿砂层、坡脚碎石垫层的阻尼作用，改变滑坡冲击力方向，使大部分冲击由下向传递转换成水平传递，冲击范围由回采区顶板区域转化到相对边帮坡脚。
