The invention discloses a waste rock and cementing layered
wedge bonding filling mining technology and a structure thereof. In the mining process through an upward horizontal
cut and fill method, upward
stoping and filling are conducted by adoption of
layers with the depth being 3-4 m; three
layers serve as a section; the first layer and the third layer are separately subjected to cementing filling through
tailings; the second layer in the middle is filled with waste rock in a spaced and
mixed mode; the bottom face pavement range is set according to the size of a stope, and a certain distance is kept from the periphery; and the periphery of a waste rock
pile is still subjected to cementing filling through
tailings, and the
tailings are in contact and connection with cementing filling bodies of the upper layer and the lower layer. By adoption of the waste rock and cementing layered
wedge bonding filling mining technology and the structure thereof, the problems that in the prior art, technologies are complex, the cost is high, the labor productivity and the ore block production capacity are relatively low, and waste rock cannot be reasonably applied are solved, and by adoption of a layered
wedge bonding mixed filling method, the strength of the filling bodies is ensured, a large amount of downhole waste rock is consumed, cementing
filling materials are saved, and the layered wedge bonding mixed filling method has the characteristics of being safe in operation, high in filling efficiency and low in cost.
