Abstract

The invention discloses a mine efficient filling retaining wall and a construction method thereof. The mine efficient filling retaining wall comprises a skeleton structure layer, blocking layers and aconcrete layer. The skeleton structure layer comprises longitudinal ribs, transverse ribs, a top plate and a metal mesh. The blocking layers are connected with the skeleton structure layer, and the concrete layer is located between the blocking layers. The blocking layers adopt jute bags. The concrete layer is made of sprayed concrete. A sprayed concrete thickness point stick, a filling pipe, anoverflow pipe and a water filtering pipe are arranged on the top plate. The sprayed concrete thickness point stick penetrates through the metal mesh to be located in the concrete layer. Materials suchas down-hole wasted steel and the jute bags are sufficiently utilized, meanwhile the construction method further has the advantages of short construction period, simple technological process, convenient operation and the like, the filling efficiency can be effectively improved, and thus safe, economical and efficient production work of a filling mining method is achieved.

Description

technical field [0001] The invention relates to the technical field of underground mining in mines, in particular to a high-efficiency mine filling retaining wall and a construction method thereof. Background technique [0002] With the adjustment of national energy and environmental protection policies, the concept of green mining has been put forward, making the filling and filling mining method applied by more and more mines. [0003] A detachable filling retaining wall with the patent number CN201620171859.3 is now disclosed, including mining access roads, joint lanes, filling pipes and exhaust pipes, which are characterized by steel skeletons, steel mesh and geotextiles; steel skeletons It is composed of columns and beams, and the upper end of the top brace is connected to the beam. The lower end of the top brace is against the bottom plate and fixed with anchor rods; the columns and beams are set in the pre-excavated annular groove, the back of the column is connected ...
