Single hydraulic props commonly used in coal mines are divided into internal injection types Single hydraulic prop, external injection single hydraulic prop and suspended single hydraulic prop. Among them, the internal injection single hydraulic prop plays a great supporting role in mining tunnels.
Introduction to the internal-injection single hydraulic prop:
The internal-injection single hydraulic prop is a constant resistance prop, which is suitable for supporting the roof of general mechanized mining working faces in coal mines when used with metal hinged roof beams. , can also be used for end support or temporary support of comprehensive mechanized coal mining working faces.
The internal injection single hydraulic prop is suitable for roof support and end head support of coal mine working faces. Due to its large load-bearing capacity, strong anti-eccentric load ability, large working stroke and wide range of use, it has It can be used in thin coal seams, medium-thick coal seams and thick coal seam working faces.
The scope of application of the internal injection single hydraulic prop:
Coal seam inclination angle: The gently inclined mining working face with a coal seam inclination angle of less than 3 can also be used in the mining working face with an inclination angle of ~3 after taking certain safety measures.
, height: not greater than the maximum height of the pillar, that is, the maximum support height of the type pillar is ., the range of support height variation is generally .3~. The maximum support height of the type pillar is ., the variation range of the support height is generally .~. etc.
During the pressure-bearing process, the middle part of the pillar should not be used as the fulcrum of the push-slide jack.
When used in the blasting mining working surface, measures should be taken to prevent the surface of the live column from being collapsed.
