Embodiment Construction

[0017] Embodiment The Shaba Mine used by Kailin (Group) Co., Ltd. is a mine under the Mining Corporation of Guizhou Kailin Group Co., Ltd., and its geological reserves are more than 50 million tons. The mine's original mining method was the open field method. The height of the middle section is 50 meters, the height of the sections is 10 meters, the length of the stope is 10-12 meters, and a 4-meter column is left between the stope and the stope.

[0018] Use the phosphogypsum cementing and then filling mining method of the present invention to divide the ore block with a strike length of 1100m into two panels along the strike, and each panel is divided into 5 layers, and the vertical height of each layer is 10m. The panel slope is arranged in the middle of each ore block. When the panel slope is constructed to the elevation of each layer, the layered roadway outside the vein that is 15m away from the ore body roof line is excavated in the roof of the ore body, and then Accor...

Abstract

The invention discloses a stuff mining method when the ardealite adhesive is solidified and relative pulp production. The stuff mining method comprises that preparing mine house, stuffing preparation, preparing pulp, and stuffing. The pulp preparation comprises that using ardealite, coal powder / dolostone and cement as the stuff material to be added into water and mixed into stuff pulp; the stuff pulp via the stuff drill hole or the pump station is input to the upper outer flat channel of the mining field via the stuff tube, to be fed into the mining field. The inventive stuff mining method can confirm the yield and stability of mine, to improve the recycle rate of mineral and protect the environment.

Description

technical field [0001] The invention relates to a mining method, and also relates to a method for filling a goaf in an underground mine, in particular to a slurry cemented filling mining method and a pulping process thereof. Background technique [0002] In the existing open-field mining method, since the goaf is not effectively treated after the ore is mined, a large number of goafs will be formed after a long period of mining, resulting in the collapse of the roof rock in the goaf and the settlement of the overlying strata. Destroy until it causes surface mountain collapses and landslides, forming geological disasters, unsafe mine production, and a great threat to surface industrial facilities, roads and houses; it will also cause damage to cultivated land, occupying a large amount of cultivated land and draining gangue, bringing many Environmental issues. In recent years, people have developed some filling mining methods for the stubborn problem of open-field mining in m...
