How to select a single hydraulic prop for mining? Single hydraulic prop for mining, double telescopic hydraulic prop, single hydraulic prop parameters, Shandong single hydraulic prop, Zibo single hydraulic prop, external injection single hydraulic prop, single hydraulic prop specifications< br/> The single hydraulic prop is a new environmentally friendly support equipment. It can be used with metal hinged roof beams for high-end general mining and artillery working face support roofs and fully mechanized mining working face support ends. It can be used as a separate point column or other temporary support.
The single hydraulic prop is suitable for inclined coal seam mining working faces where the coal seam inclination angle is less than 3 degrees. The conditions for the coal seam roof and floor that it adapts to are: the backwardness of the roof does not affect the recovery of the pillars, the bottom plate should not be too soft, and the depth of the pillars pressed into the bottom plate Do not deteriorate the integrity of the base plate, otherwise the base should be enlarged. When used in blasting mining working surfaces where coal is relatively soft, protective measures should be taken on the coating surface of the living cylinder to prevent collapse. When the pillars are matched with wooden roof beams or used as point columns, the top caps should be replaced with column caps to avoid damaging the wooden beams.
Single hydraulic prop product classification
According to the different liquid supply methods and working fluids, props are divided into external liquid supply type (referred to as external injection type) and internal liquid supply type (referred to as internal injection type) props.
According to different working strokes, the pillars are divided into single telescopic (single stroke) pillars and double telescopic (double stroke) pillars. When the stroke characteristics are not specified, they are single telescopic pillars.
According to different materials used, pillars are divided into ordinary steel pillars, high titanium alloy pillars, aluminum alloy pillars, stainless steel pillars, etc. When the material characteristics are not specified, they are steel pillars.
According to the structural form, the pillars can be divided into two categories: piston pillars and plunger suspended pillars. Piston-type props are divided into single telescopic and double telescopic props according to their working stroke. The plunger suspended pillar uses water medium and is an environmentally friendly pillar.
