Description

Technical Field

[0001] The invention relates to the technical field of mine drainage, in particular to mine drainage equipment. Background Art

[0002] Blast holes are a key link in the entire underground mining system and play a very important role in the mine shaft and tunnel construction and mining process. Blast holes are drilled using rock drilling equipment, and charged using charging equipment or manually. After blasting, the ore and rock collapse from the rock mass and are shoveled away using shovel-loading equipment.

[0003] During mining, explosives must be placed in the boreholes for blasting operations. Especially in open-pit mining blasting, the drilled blastholes are exposed on the surface of the ore rock. Due to rain or infiltration, water often accumulates in the drilled blastholes, making blasting impossible. The water in the blastholes must be drained.

[0004] However, when using the existing blasthole drainage equipment, it is difficult to adopt different drainage equipment according to the geographical environment; for example, in some mines with complex terrain and difficult for large machines or power equipment to enter, it is difficult to drain the blastholes in such terrain; at the same time, when the drainage equipment is draining, it is difficult to extract the water flow in the blasthole and discharge the water in the drainage pipe at the same time, so that the water flow in the drainage pipe circulates. For example, the Chinese invention patent with patent number CN110630323A effectively solves the above problems, but the equipment in the above patent cannot be expanded, and the length of the mine blasthole is usually between several meters and more than ten meters. The equipment in the above patent is suitable for shallower blastholes and is difficult to play a role when encountering some deeper blastholes. Summary of the invention

The water accumulated in some deeper mine blastholes can be pumped out, which can effectively prevent excessive water accumulation in the mine blastholes, thereby avoiding affecting the explosion effect of the explosives in the blastholes, and the expandable drainage component can drain water by two methods: manual drainage without electricity and water pump assisted drainage.

[0049] Furthermore, the flange plate 403 is provided with a plurality of mounting holes, and the water inside the mine blasthole can be pumped out by docking and mounting the pipe of the water pump with the flange plate 403;

[0050] Furthermore, when pumping water, secondary filtration is performed through the fine filter 106 and the coarse filter 109 at the bottom of the water inlet pipe 100 to filter out larger gravel and fine sand and gravel to prevent damage to the pump blades and the air bag 501.

[0051] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.

Claims
