Abstract
Description
technical field
[0001] The invention relates to the technical field of mining roadway layout in coal mines, in particular to a double-lane chain filling mining layout structure. Background technique
[0002] The mining of coal resources in the past has caused serious subsidence damage and ecological environment problems. Mining subsidence and open-air discharge of coal gangue are the main sources of problems that cause damage and affect the environment of mining areas. The amount of coal pressed under buildings in our country is large, especially in villages, and the amount of coal pressed in some mining areas or minefield villages even exceeds 60% of the total reserves. The problem of coal pressure under the village has become the main problem faced by some mining areas. At present, this problem is mainly solved by the layout structure of double-lane chain filling and mining. The existing double-lane chain filling and mining layout structure needs Coal pillars of a certain...
Examples
Embodiment
[0025] refer to Figure 1-5 , this embodiment proposes a double-lane chain filling mining layout structure, including a mining lane 1, a horizontal lane 2 is arranged on the mining lane 1, a coal pillar 3 is built in the horizontal lane 2, and a movable seat is arranged in the horizontal lane 2 4. Two side plates 5 are welded on one side of the moving seat 4, and a first plate 6 is welded on the side of the upper side plate 5 away from the moving seat 4, and a second plate 7 is welded on the top of the first plate 6. The bottom of the second plate 7 is provided with a mounting groove 8, and a rotating motor 9 is installed in the mounting groove 8. The output shaft of the rotating motor 9 is welded with a rotating shaft 10, and the top of the side plate 5 is provided with a rotating hole 11, and the rotating shaft 10 is rotated and installed. In the rotating hole 11, two slide grooves 12 are provided on one side of the moving seat 4, and a slide plate 13 is slidably installed i...
