Technical Field
The utility model relates to a coal mine equipment technical field specifically is a special safety relief valve of defeated stuff pump.
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.
The method is characterized in that suburb coal mine exploration and defense teams set up underground slurry conveying pump stations in all mining areas, cement slurry is conveyed to all drill sites of a working face through laid slurry conveying pipelines for buried pipe, shallow grouting reinforcement and hole sealing.
