  • To solve the problem of the high concentration of coal dust when the coal is drawn from the hydraulic support,we designed a negative-pressure remover which was installed on the hydraulic support tail beam;determined the installation position combining with the parameters of the hydraulic support and got the biggest size of the negative-pressure remover;we chose different diameters of the ejecting cone with the laboratory test conditions and built up and mesh the 3D models of the negative-pressure remover;we used the Fluent-analysis software to simulate the models with different jet flowing velocities and got the best combining parameters of the jet flowing velocity and ejecting cone diameter,which provides some basis for the next optimization for the negative-pressure remover.
