Description

Coal mine excavation blasthole plugging device

Technical Field

The utility model relates to a colliery equipment of digging technical field, more specifically say, relate to a big gun hole plugging device is excavated in colliery.

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 coal is generally 46 to 97%, brown to black, and has a dull to metallic luster. According to the degree of coalification, coal can be classified into peat, lignite, bituminous coal and anthracite.

At present, when coal mining is carried out in the field of coal mines, gunpowder is often required to be used for blasting an ore body, the gunpowder is inserted into a blasthole after the ore body is drilled into a certain depth, in order to improve blasting quality and efficiency, the blasthole is plugged, so that the explosive force is concentrated around the gunpowder, a common plugging mode is to fill water stemming in the depth of the blasthole, and the remaining blasthole part outside the water stemming is sealed by adopting clay stemming and the like, so that the blasthole is completely sealed. When carrying out clay bubble mud and filling, the mode of commonly using adopts the manual work to send into clay bubble mud in the big gun eye, then compresses tightly clay bubble mud through instruments such as wooden stick, accomplish and pack, when the big gun eye degree of depth is darker, compress tightly the tamping behind the clay bubble mud of disposable filling capacity, the stickness between clay and the big gun eye is great, it is comparatively hard to compress tightly the tamping action, extravagant operation personnel physical power, adopt the mode that adds many times and compress tightly the tamping, then extravagant a large amount of vigor, influence the operating efficiency, the effect is not good.
