DWL-type hydraulic prop was a slight increase of resistance of metal pillar friction metal pillars supporting the roof for the use of coal face. Early work with the resistance of metal pillar can be high and large shrinkage characteristics. Prop to set the beginning of the work soon after the resistance, early to play the supporting role on the roof. Metal roof pillar subsidence can also be used for larger, have periodic face pressure. 
 D-W-hydraulic prop on behalf of representatives of injection for 45 - maximum height of the pillars 200 - rated as the pillar of the resistance of 110 - as the pillar of the cylinder diameter 
 Mine for the constant resistance of hydraulic prop-style pillars, which can meet with a variety of roof beams, columns can also decide to use. Mechanized mining for coal or general support items Blasting Face boards are also available for mechanized coal face end support or other use of temporary support. 
 Mine hydraulic prop, the use of advanced EDA corrosion process, so that the surface anti-corrosion ability of living doubled cylinder. In use, even if the surface of living stabbed or seriously bump cylinder, leaving the bare substrate exposed will not cause corrosion of the substrate or coating off a large area. ASTRI developed by Beijing coal, after years of use of our plant, this process has reached domestic leading level. The appearance of the product color is military green, with zinc and nickel, passivation of the surface of dark green, silicone coating, the zinc phosphate anti-corrosion ability to process more than 3 times, the use of zinc-nickel coating, and coating of the active pillar potential difference between the lower and difficult to form the original cells, the impact when the coating was destroyed, resulting in self-protection, for blasting coal face to use.
