Description

Reinforced coal mine roof waterproof flow guide device

Technical Field

The utility model relates to a colliery mechanical equipment technical field specifically is a waterproof guiding device of reinforcement type colliery roof.

Background

Coal mines are areas where humans mine coal resources in coal-rich mining areas, and are generally divided into underground coal mines and opencast coal mines. When the coal seam is far from the ground surface, a tunnel is usually dug to the underground, so that the coal is a mineworker coal mine. When the coal seam is very close to the earth surface, the coal is generally excavated by directly stripping the earth surface, which is an open pit coal mine. The vast majority of coal mines in China belong to underground coal mines. Coal mines encompass a large area above ground and below ground as well as associated facilities. Coal mines are reasonable spaces excavated by humans when excavating geological formations rich in coal and generally include roadways, wells, and mining surfaces, among others.

Coal is the most predominant solid fuel, one of the flammable organic rocks. It is formed by that the flourishing plants grown in a certain geologic age are gradually piled up into a thick layer in a proper geologic environment, and are buried in the water bottom or silt, and then are subjected to the natural coalification action in a long geologic age. In the geologic periods of the world, most coal is produced in the stratums of the stone charm, the pilaster, the Jurassic and the third era, which is an important coal-forming era. The carbon content of the coal is generally 46-97%, and the coal is brown to black and has dull to metallic luster. According to the degree of coalification, coal can be classified into peat, lignite, bituminous coal and anthracite.

When the coal seam is close to the surface of the earth, the open pit mining mode is economical. Most coal seams are far from the surface, so open pit mining cannot be used. Underground mining accounts for 60% of the world's coal production. In a mine pit, the roof-and-column method is typically used to advance through the coal seam, with the beams and columns being used to support the pit. There are four major underground mining methods: longwall mining, continuous mining, blast mining, and shortwall mining.

In the coal mining process, although a coal mining roadway is supported by a top plate and sucks the underground water layer to a certain extent, a certain safety protection effect is achieved, residual water of the underground water layer still flows into the roadway through a gap of the top plate, so that a bottom plate is wet and slippery, and the safety of workers is affected; when the roadway bottom plate is in a humid environment for a long time, the mudstone of the bottom plate can expand when meeting water, so that the bottom plate swells, the belt frame is inclined, and the production safety is seriously influenced.

In order to ensure the safety of mining, the publication No. CN201821590751.3 discloses a coal mine roof waterproof diversion device, which solves the above problems by dredging water flow, but the device still has some disadvantages, such as the support part in the device is troublesome to adjust and has insufficient stability, especially when adjusting the turnbuckle, the lower support plate will move along with the turnbuckle, and the stability is poor.
