Introduction:

Single hydraulic prop for seam angle is less than 25 degrees - 35 degrees inclined coal seam mining face, the adaptation of the coal seam roof and floor conditions are: roof pillars behind do not affect the recovery of base should not be too soft, prop depth is not pressed into the floor deterioration of the integrity of the base plate, or should increase the base. In the coal mining face relatively loose cannon when used on the live cylinder coating surface to take protective measures to prevent collapse. With wooden roof beams and pillars or columns used to do, you should replace the column caps cover to prevent damage to wooden beams.

Description:

Hydraulic prop for the latest contemporary repair methods to polymer composites based. Which has excellent adhesion and good compressive strength, not only to meet the requirements of the conditions of the production and operation process is simple, neither heat affected, coating thickness and unrestricted. While the coating itself has excellent corrosion resistance and oil self-lubricating function to ensure the wear resistance after the repair, to ensure normal production, to avoid damage to equipment components increased.
