Stent used by the valve group, column, jack, are not allowed in the underground demolition inspection, the overall replacement. Replace the cylinder as far as possible before the shortest, the joints should be installed on the dust cap
these actions by the emulsion pump Station supply of high-pressure liquid, through a variety of valve control column, jack to achieve the expansion and contraction.
he hydraulic support in the course of the work not only to be able to reliably support the roof and should be able to move along with the propulsion forward movement, requiring hydraulic support must have up, down, push, move four basic movements,
Hydraulic support is used to control the coal mining face pressure structure of the mine. The surface pressure is applied to the hydraulic support. In the mechanical system where the hydraulic support and the face rock are interacted, if the supporting force of the hydraulic support is exactly the same as the external force acting on the hydraulic support,
