Abstract
The invention discloses a wall-mounting-type vertical coal bunker without a coal feeder chamber. The wall-mounting-type upright coal bunker comprises a vertical cylindrical reinforced concrete bunker body and a cone-frustum-shaped necking opening in the lower portion of the bunker body. An H-beam steel joist and an H-beam steel bunker body bracket which play a role in load bearing are embedded inside bunker wall rock and used for supporting the reinforced concrete bunker body. A load-bearing anchor rope which is embedded into the reinforced concrete bunker body and inserted into the bunker wall rock is arranged at the position, arranged inside the cone-frustum-shaped necking opening, of the H-beam steel bunker body bracket. A tray and a locking tool are arranged at the position, located inside the reinforced concrete bunker body, of the load-bearing anchor rope, wherein the tray plays a role in load bearing, and the locking tool is used for fixing the tray. The loading-bearing anchor rope, the H-beam steel bunker body bracket, an H-beam steel bunker body bracket fixed anchor rope and an H-beam steel bracket jointly support the reinforced concrete bunker body and coal inside the bunker body. According to the wall-mounting-type vertical coal bunker, the chamber special for a coal feeder of an existing coal bunker is eliminated, and the difficult problem that due to the fact that the surrounding rock of the coal feeder chamber is easily affected by factors like water and pressure, and especially due to the intense heaving floor of the coal feeder chamber, the coal bunker can not be safely and efficiently used is solved.
Description
Technical field
The present invention relates to erect coal bin at the bottom of a kind of coal mine, especially a kind of wall-hanging erect coal bin not having loading gallery being applicable to Floor Heave in Roadway below coal bunker.
Background technology
Existing underground coal mine erect coal bin bottom all has a special loading gallery, and this chamber carries the total weight of coal, concrete warehouse and feeder in coal bunker.Therefore, the stabilized soil pavement of loading gallery be coal bunker can normal safe use key point.Common loading gallery two is helped to be concrete side wall that intensity is higher or concrete column, when coal bunker load act on two help on concrete side wall or concrete column time, under the effect of the two pressing mold effects helping concrete side wall or concrete column, far field stress and water, country rock is constantly to squeezing flow in chamber, and then cause moving and inclination in both walls or column generation, finally make loading gallery be difficult to because of the sharply reduction of its monocoque structure stability carrying of remaining valid.Prior art is by artificially improving loading gallery supporting intensity, Surrounding Rock Strength and taking the methods such as effective drainage measure, but all can not fundamentally solve coal bunker because of loading gallery country rock be subject to the factor such as water, pressure impact, particularly the strong pucking of loading gallery cause coal bunker can not safety, effective use a difficult problem.
