Experimental study on stoping residual pillar of steep dip and medium thickness orebody by consolidated fill method of spacing shock proof technology
Ji Hongzhai et al. (Da He Gold Mine of Zhaoyuan City)
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.
