间隔防震胶结充填回采急倾斜中厚残留矿柱的试验研究

Experimental study on stoping residual pillar of steep dip and medium thickness orebody by consolidated fill method of spacing shock proof technology

大河金矿针对古采区的急倾斜残留矿柱及其下盘贫矿体的回采情况，曾用胶结充填法对残留矿柱先采，再用尾砂充填法对下盘贫矿体后采的间隔防震工艺进行试验，为保护矿体上盘的村庄与水利设施。

According to the condition of steep dip residual pillar in the ancient mined out area and the stoping situation of barren orebody in the lower side wall,Da He Gold Mine made an experiment of spacing shock proof technology,I.e. empolying consolidated fill method to mine residual pillar at first,then employing tail filling method to mine barren orebody at the lower side wall.This made a better contribution to the necessity of mine production and to the protection against village's collapse and the damage of water conservancy facilities on the upper side wall of orebody.
