Mining filling method

The present invention discloses a fill mining method, comprising the steps of: a first step the ore mined ore mining field; a first step of filling the goaf stope filled with binder-containing slurry; mined ore the second field of ore mining step; a third step of filling the second step stope filling slurry containing a binder and a goaf ore mining field adjacent to the filling area and is filled with a binder-free a second step of filling the slurry stope goaf other regions; a third step of mining ore mining field; and a binder-free filling with slurry fill goaf third step stope. The mining method of the present invention is filled, after mining, the second step and the third step stope stope fill area adjacent to the filling using the filling slurry containing binder, the second step of the stope other parts not containing binder filling slurry filled, therefore, the present invention may be filled to ensure a reasonable strength distribution goaf, cementation and filling ratio of the second reduction step of the stope, filling a low cost, while the greatest degree of mining ore, improve resource utilization, improved economic benefits.
