Embodiment Construction

[0017] Example The Shaba Mine for Kailin (Group) is a subordinate mine of Guizhou Kailin Group Corporation Mining Corporation, and its retained geological reserves are more than 50 million tons. The original mining method of the mine was the empty 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 there is a column of 4 meters between the stope and the stope.

[0018] Using the phosphogypsum cemented subsequent filling mining method of the present invention, the ore block with a strike length of 1100m is divided into two panels along the strike, each panel is divided into 5 layers, and each layer has a vertical height of 10m. The panel ramp is arranged in the middle of each ore block. When the panel ramp is constructed to the elevation of each layer, it is arranged in the orebody roof 15m away from the orebody roof line and the vein layered roadway, then Enter each ore house according t...

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 filling material in an underground goaf, in particular, to a slurry cemented filling mining method and a slurry making process. Background technique [0002] Existing open-field mining, because the mined-out area is not effectively processed after the ore is mined, after a long period of mining, a large number of mined-out areas will be formed, causing the roof rock of the mined-out area to collapse and the overlying rock layer to settle. Destruction, until it causes surface mountain collapse and landslides, forms geological disasters, mine production is unsafe, and poses great threats to surface industrial facilities, roads and houses; it also causes damage to cultivated land, takes up a large amount of cultivated land to discharge waste, and brings many environmental issue. In recent years, people have developed some filling mining methods in response to the stubborn prob...
