Problems solved by technology
Vertical coal bunker: It can be made into a circular shape, with high section utilization rate, convenient construction, low maintenance cost, not easy to block the bunker, and easy to use, but the lump coal breakage rate is high
Inclined coal bunker: The crushing rate of lump coal is low, but the construction of the bunker body is difficult, the maintenance cost is high, the bunker is prone to blockage accidents, and it is inconvenient to use
The horizontal coal bunker has many twists and turns, which is inconvenient for construction and easy to block the bunker, and the lump coal is easy to break, so it is rarely used on site
It is difficult for the above-mentioned coal bunkers to meet the requirements of not only convenient construction and use, but also the ability to increase the lump coal rate.

specific Embodiment
[0028] A circular roadway with a diameter of 25 meters is constructed in the underground rock mass, with a circumference of 80 meters and a circular surface inclination of 8-10 degrees. A 900mm-gauge circular track is laid on the bottom plate, and a cart is installed as the driving force of the mine car. The movement is 5 Ton bottom unloading mine car, the upper end of the circular inclined roadway is connected to the upper coal conveying belt, and the lower part is connected to the lower unloading bin.
[0029] When the transportation is normal, the coal is loaded sequentially and runs in a clockwise direction. When it runs to the bottom of the circular roadway, it is automatically unloaded, and the empty car goes up the circular road. The operation process is: loading, heavy vehicles descending, reaching the bottom for unloading, empty vehicles ascending, and reaching the top for loading.
[0030] If the lower part cannot be unloaded and needs to store coal, the heavy trucks...

The present invention relates to a circular mine tandem type anti-breaking bunker, including mine car, runway and belt conveyor, and said coal bunker is equipped with circular bunker channel, and thecircular surface of the bunker channel is made into oblique plane whose inlet end is higher and outlet end is lower, and which are formed into an oblique angle alpha, a circular trackway is laid on the bottom plate of the circular bunker channel, and the mine car group in which the mine cars are series-connected into circular form is placed on the trackway. Said low outlet end of the bunker is communicated with lower transport equipment, so that it can prevent coal block from being broken and raise coal block rate.
Description
technical field [0001] The invention relates to a transportation and storage facility for coal production, in particular to an annular string car type anti-shattering coal bunker. Background technique [0002] Lump coal is a high value-added product of coal mines. Generally, the unit price of lump coal is about 100 yuan higher than that of the same type of coal. Increasing coal lump coal rate is an important way for coal enterprises to increase economic benefits. With the rapid development of the modern economy, the requirements for lump coal at home and abroad have increased substantially, and lump coal occupies a large proportion in the coal market, and at the same time, there are stricter requirements for its quality. In the process of production, transportation and storage, anti-breakage has become an important issue to ensure a certain lump coal rate. However, the key part where the crushing occurs is the coal bunker, and the coal bunker is an important chamber that r...
