Development method of transportation through auxiliary slope ramp matched with rubber belt inclined shaft

Abstract

The invention discloses a development method of transportation through an auxiliary slope ramp matched with a rubber belt inclined shaft. During the process of infrastructure construction, tunneling of the rubber belt inclined shaft and the auxiliary slope ramp is simultaneously performed; the auxiliary slope ramp comprises auxiliary slope straight ways which are arranged at 0 to 8 degrees and spiral turn-back ways which are connected alternately; the height of the auxiliary slope ramp is the same as that of the rubber belt inclined shaft in a position where the auxiliary slope ramp is adjacent to the rubber belt inclined shaft by descending along the spiral turn-back way; a connection roadway is arranged every 300 to 400m to communicate the rubber belt inclined shaft with the auxiliary slope ramp, and the shaft at the inclined end of the rubber belt is higher than that of the auxiliary slope ramp; in an ore bed, the rubber belt inclined shaft and the auxiliary slope ramp are distributed on dike, and middle section travelling roadways are distributed in the dike; the middle section travelling roadways are communicated with one another through the auxiliary slope ramp; the middle section travelling roadways are communicated with fragmented travelling roadways through a panel slope ramp; and middle section ore is lowered to the rubber belt inclined shaft through the panel slope ramp and a drop shaft and is transported to the earth surface. By adopting the method, ventilation, drainage and overhaul are facilitated during tunneling, the transportation capability is high, and the transportation cost is low.

Description

technical field

[0001] The invention relates to an underground mine development method, in particular to a mine shaft development method suitable for underground non-shaft lifting. Background technique

[0002] According to the occurrence conditions of the ore body, most of the sedimentary mines have a large burial depth and a gentle inclination angle of the ore body, so only inclined shafts or vertical shafts are suitable for development.

[0003] Compared with the development of inclined shafts, the development of vertical shafts has the advantages of shorter shafts and shorter lengths of drainage pipelines, but it is difficult to extend the depth of the shafts and needs to be built at one time. The inclination angle of the body is slow, and the engineering volume of the stone gate is relatively large; when the skip is lifted, it is necessary to set up a slide shaft to concentrate the ore, and the ore is lowered first and then lifted, resulting in a waste of energy and pow...
