Flexible self-wall-attached sealing wall for mines and construction method thereof

Abstract

The invention discloses a flexible self-wall-attached sealing wall for mines, which relates to the technical field of coal mine safety construction. The sealing wall comprises a sealing wall main body, wherein the periphery of the sealing wall main body is provided with flexible self-wall-attached composite modules. According to the flexible self-wall-attached sealing wall for mines, the peripheryof the sealing wall man body is provided with the flexible self-wall-attached composite modules which are prefabricated by flexible flame retardant composite materials and are arranged in cuts on theperiphery of a roadway, under the condition of strong underground pressure of the coal mine, the flexible materials are shrunk under the pressure, the elastic energy is accumulated, and the flexiblematerial can be more closely fit to the peripheral walls of the roadway, thereby realizing the self wall attachment, and effectively preventing the air leakage on the periphery of the sealing wall; and meanwhile, the flexible self-wall-attached composite modules are shrunk under the pressure to form a buffering effect, so that the energy of the mine pressure directly acting on the sealing wall main body can be reduced, and an effect for protecting the sealing wall main body can be achieved.

Description

technical field [0001] The invention relates to the technical field of coal mine safety construction, in particular to a flexible self-attached closed wall for mines and a construction method thereof. Background technique [0002] In order to prevent the poisonous and harmful gas in the goaf from pouring into the mining space, the method of building a closed wall is often used to isolate the goaf from the ventilation system. At present, the conventional construction method of the airtight wall is to build two thin walls with bricks, the two form a bearing space, and then pour concrete or yellow mud and other fillers into the middle to form an airtight wall. This method not only has a long construction period, complex technical construction methods, and consumes a lot of human resources, but also forms a closed wall that lacks toughness. Under the action of mine pressure, it itself, especially the junction between its periphery and the coal wall, is easily cracked, resulting ...

Problems solved by technology

This method not only has a long construction period, complex technical construction methods, and consumes a lot of human resources, but also forms a closed wall that lacks toughness. Under the action of mine pressure, it itself, especially the junction between its periphery and the coal wall, is easily cracked, resulting in airtight air leakage. , causing gas leakage or oxygen intrusion, which can easily lead to disasters such as explosions or fires
