From the principle of speaking, it has been a long time retire hydraulic mining technology used in coal mine inour country is basically the same, are the jet formed the water with certain pressure through the nozzle diameter smaller, the jets asa tool for cutting, crushing and cleaning materials. The difference is only the pressure of high pressure water jet nozzle diameter, the higher the finer. The use of hydraulic mining of water pressure is usually 5~15MP, nozzle outlet diameter is 15~30mm; and high water pressure water jet in general is in 30MP above, some up to several hundred MPa, nozzle diameter is less than 2mm, the minimum up to . Therefore, the high pressure water jet can focus the enormous energy ina small area, such asa bundle of energy density of high pressure water jet 100MP pete with laser beam. This graduation design topic is the design of shearer cutting water jet device. Mainly elaborated the high pressure water jet technology in coal mining machine on the application background, advantages and disadvantages and the problems need tobe resolved such content. High pressure water jet breaking coal and coal mining machine joint isa new technology, but also a lotof
