Embodiment Construction

[0025] In order to make the technical problems, technical solutions and advantages to be solved by the present invention clearer, the following will describe in detail with reference to the drawings and specific embodiments.

[0026] The present invention aims at the problems of long period, cumbersome construction, poor compatibility of the reinforcement of the filling body, easy separation and the like in the current filling false roof construction, and provides an artificial false roof construction method with a built-in basalt fiber geogrid reinforcement structure.

[0027] The method includes steps as follows:

[0028] (1) After the mining is completed, level the site, clean up the large waste rocks existing in the approach, and deal with the two groups of protruding pumice;

[0029] (2) Cut the basalt fiber grid according to the size of the stope to ensure that the basalt fiber grid is a whole in the span and length direction of the stope, and cut three pieces of basalt ...

Abstract

The invention provides an artificial false roof construction method of a built-in basalt fiber geogrid reinforced structure, and belongs to the technical field of mining filling false roof manufacturing. The method comprises the steps that after mining is finished, a site is leveled, large waste stones existing in an access road are removed, and pumice stones protruding out of the two sides are treated; basalt fiber grids are cut according to the size of a stope, the basalt fiber grids are a whole in the span and length direction of the stope, and the three basalt fiber grids are cut to be arranged in a filling body in an upper layer, a middle layer and a lower layer; and then two layers of expansion screws are arranged along the side of the stope, finally, the expansion screws are arranged in the stope from inside to outside, and the three basalt fiber grids are arranged into three layers from top to bottom. According to the method, the false roof filling process is simple, integrity is high, safety is high, and cost is low.

Description

technical field [0001] The invention relates to the technical field of false roof production for mining filling, in particular to an artificial false roof construction method with a built-in basalt fiber geogrid reinforcement structure. Background technique [0002] In order to improve the recovery rate of precious metals such as gold, the filling method is usually used for mining. The downward horizontal layered filling method is a mining method aimed at the formation of extremely broken ore bodies. This method builds the artificial false roof of the next layer during the process of mining the previous layer, and backfills the next layer under the protection of the artificial false roof. Therefore, the stability of the filling false roof is directly related to the mining of the ore body. The construction of a stable and reliable filling false roof is one of the key procedures of this method. [0003] At present, the construction procedures of artificial false roof construc...
