Problems solved by technology

[0005] Based on this, it is necessary to solve the above-mentioned problems such as poor connection between the artificial dam body and the coal body and the inability to realize reuse, etc., to innovate, develop and design a new type of coal mine underground reservoir dam body, and realize the adjustment of the artificial dam body and the coal body according to the water pressure change in the underground reservoir. The extrusion force can be automatically adjusted, and it can be reused many times, reducing the cost of construction and use of underground reservoirs in coal mines

Abstract

The invention discloses a reusable coal mine underground reservoir dam body with an automatic tensioning function, the main structure of which includes a first load-bearing telescopic frame, a second load-bearing telescopic frame, a third load-bearing telescopic frame, a fourth load-bearing telescopic frame, and a sealing plate , sealed air bag, the first frame connecting plate, the second frame connecting plate, telescopic oil cylinder; the present invention makes full use of the change of water pressure in the underground reservoir to realize the automatic adjustment of the extrusion force between the artificial dam body and the coal body, and can realize Repeated use, the invention has the advantages of simple structure, reliability, and practicality, which greatly improves the sealing effect of the dam body and reduces the cost of building the dam.

Description

technical field [0001] The invention relates to an artificial dam body of a coal mine underground reservoir, in particular to a coal mine underground reservoir dam body that can be automatically tensioned according to changes in water pressure in the coal mine underground reservoir and can be reused, which can effectively improve the water resistance of the dam body performance and reduce the cost of construction and use of the dam. Background technique [0002] The protection and utilization of water resources in coal mining is a major technical problem for coal safety and green development. my country’s coal development produces about 10 billion tons of mine water every year, but the effective utilization rate is only about 25%. The direct discharge of mine water to the surface has caused water resources a lot of waste. Underground reservoirs in coal mines store, filter, absorb, ion exchange, etc. mine water by using the gaps and fissures of rocks falling from the goaf of ...
