Hydraulic prop
The series of DW outer-injected single hydraulic prop can be used fro supporting the roof of mining coal face independently.
The series of DW outer-injected single hydraulic prop can be used fro supporting the roof of mining coal face independently or associated with slide bar or link bar. It is suitable for gently inclined seamw ith a gradient less than25 degree. If safety measures are taken, it is also for coal face with gradient up to 25-35degree. Besides, it can be used as an end support in a fully mechanized mining coal face.
