Problems solved by technology

However, vertical warehouses and inclined warehouses must have a certain space height before they can be constructed. Due to the constraints of underground geological conditions and comprehensive layout of other shafts, the construction is difficult, the cost is high, the amount of maintenance is large, the coal is easily broken, and the lump coal rate is low. , affecting the economic benefits of coal enterprises

Embodiment Construction

[0021] Please refer to Fig. 1 and Fig. 2. The present invention is an underground coal bunker, including a coal separator, a walking trolley, a belt conveyor, and a scraper conveyor;

[0022] In the roadway 1 with a semi-circular arch in the upper part of the cross section, a sidewalk 3 is provided between the side wall of the roadway and the belt rack 2, and a coal separator and a walking trolley 5 are erected on the track of the belt rack 2 and the middle partition wall 4 , the trolley is connected with a traction steel rope 6, a belt conveyor 7 is arranged under the coal separator, and the space between the inner side of the partition wall 4 and the outer side of the inclined partition 8 arranged in the roadway forms a coal bunker 9 with a wide top and a narrow bottom. There are several coal discharge holes 10 on the inclined partition 8, and a scraper conveyor 11 is arranged on the roadway bottom surface outside the inclined partition 8. The scraper conveyor 11 is aligned w...

Abstract

The present invention relates to an underground driftway bunker, including coal scatter, running larry, belt machine and scraper conveyor, in the tunnel whose upper portion of the cross-section is made into the form of round arch, between one side wall of the tunnel and belt frame a footway is set, and on the belt frame and track rail of middle partition wall the coal scatter and running larry are set, said larry is connected with pull steel rope, under the coal scatter the belt machine is set, and between the inner side of the partition wall and outside of inward inclined partition in the tunnel the coal bunker whose upper portion is wide and lower portion is narrow can be formed. Said invention can raise block coal rate and its construction is simple.

Description

technical field [0001] The invention relates to a storage and transportation facility in coal production, in particular to an underground coal bunker in a coal mine. Background technique [0002] In the process of underground coal production, there is often an unbalanced production. Underground coal storage bunkers can play a role in buffering and balancing. At present, coal bunkers are mostly in the form of vertical bins and inclined bins. However, vertical warehouses and inclined warehouses must have a certain space height before they can be constructed. Due to the constraints of underground geological conditions and comprehensive layout of other shafts, the construction is difficult, the cost is high, the amount of maintenance is large, the coal is easily broken, and the lump coal rate is low. , affecting the economic benefits of coal enterprises. Contents of the invention [0003] The purpose of the present invention is to overcome above-mentioned deficiency, provide ...
