Coal slurry excavating and processing method for coal mine water warehouse

Abstract

The invention relates to a method for dredging and treating coal slurry in various water sumps of coal mine, in particular to a method for dredging and treating coal slurry in a water sump of a coal mine. The method is not only applicable to the water sump of the coal mine, but also used for dredging and treatment of silt in various laneway water sumps. The method for dredging and treating the coal slurry in the water sump of the coal mine comprises the steps of diluting the coal slurry, stirring and slurry making, large-grain crushing, coal slurry conveying, cleaned coal extraction, coal slurry filter pressing (solid separation) and the like. The method can be used for automatically dredging and treating the coal slurry in various water sumps and extract the cleaned coal from the coal slurry so that the solid coal slurry is convenient to transport and store and the coal slurry is changed into valuable, and simultaneously the method improves the production efficiency.

Description

technical field [0001] The invention relates to a method for clearing and treating coal slime in various water bins in coal mines, especially a method for clearing and treating coal slime in coal mine water bins, which is not only applicable to coal mine water bins, but also can be used in various roadways The dredging and sludge treatment of type water tank silt. technical background [0002] In the coal industry, for the dredging and excavation of coal slime and silt in coal mine water bins and various roadway type water bins, some coal mine water bin slime dredging methods and equipment have gradually emerged in recent years, some of which are suitable for coarse coal slime dredging , only solve the problem of coal slime loading (such as open patent: CN101338571 etc.), although some provide a complete set of technology and equipment (publication number: CN1676879A) to coal slime from dredging to processing, but limited to fine coal slime, for coarse Granular coal slime i...

Problems solved by technology

[0002] In the coal industry, for the dredging and excavation of coal slime and silt in coal mine water bins and various roadway type water bins, some coal mine water bin slime dredging methods and equipment have gradually emerged in recent years, some of which are suitable for coarse coal slime dredging , only solve the problem of coal slime loading (such as open patent: CN101338571 etc.), although some provide a complete set of technology and equipment (publication number: CN1676879A) to coal slime from dredging to processing, but limited to fine coal slime, for coarse Granular coal slime is not suitable. Therefore, the dredging and processing of coal mine water tank slime and roadway water tank silt is a large project, a lot of manpower and material resources are invested, production costs are increased, and production efficiency is low. So far, there is no good solution.
