Filling material self-building retaining wall and construction method

Abstract

The invention discloses a filling material self-building retaining wall and a construction method, and belongs to the field of mining. In order to solve the problems that an existing filling retaining wall is high in cost and low in construction efficiency, the invention provides a filling material self-building retaining wall. The filling material self-building retaining wall comprises a plurality of filling retaining wall bodies which are arranged in a roadway from bottom to top, the filling retaining wall bodies are arranged in the roadway in a step shape, each filling retaining wall body comprises two baffles which are oppositely arranged, the edges of the two baffles are attached to surrounding rock in the roadway, the two baffles and the surrounding rock form a trapezoidal filling space, and the filling space is filled with a filling material. The filling material self-building retaining wall is built by the plurality of trapezoidal filling retaining wall bodies, the anti-sliding and anti-overturning capacities of the filling retaining wall bodies are effectively improved through the trapezoidal structures with the narrow upper portions and the wide lower portions, and then the strength and stability of the whole self-building retaining wall are improved; meanwhile, the construction method is easy to operate, the construction time is greatly shortened, and the efficiency is improved; and the filling material is adopted as the main material of the retaining wall, so that the cost is greatly reduced.

Description

technical field [0001] The invention belongs to the field of mining, and more specifically relates to a self-built retaining wall with filling materials and a construction method. Background technique [0002] Fill and fill mining method is a commonly used mining method in modern mining methods. With the advancement of the mining face in the mine, the filling mining method sends the filling material into the goaf to achieve the purpose of controlling the ground pressure in the goaf and preventing the surrounding rock from collapsing, caving and other hazards; Under mining, reduce the loss of ore dilution. With the depletion of surface resources, the mining depth continues to increase, and the proportion of filling mining methods in mines continues to increase. In the filling mining method, the construction of the filling retaining wall is an important process, and its main function is to close the goaf and prevent the goaf filling material from flowing into the connected r...
