Abstract

The invention discloses a reusable coal mine underground reservoir dam body with an automatic tensioning function. A main body structure of the reusable coal mine underground reservoir dam body comprises a first bearing telescopic frame, a second bearing telescopic frame, a third bearing telescopic frame, a fourth bearing telescopic frame, a sealing plate, a sealing air bag, a first frame connecting plate, a second frame connecting plate and a telescopic oil cylinder. According to the reusable coal mine underground reservoir dam body with the automatic tensioning function, the extrusion force on the artificial dam body and a coal body is automatically adjusted by fully utilizing the change of the water pressure in an underground reservoir, and repeated use is achieved; the reusable coal mine underground reservoir dam body with the automatic tensioning function has the advantages of simple structure, reliability, practicability and the like, the sealing effect of the dam body is greatly improved, and the dam building cost is reduced.

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 ...
