High initial bracing force
The initial bracing force of Hydraulic Prop is one of its important performance indicators. For example, the initial support force of monolithic Hydraulic Prop can reach 70100KN, which is 310 times of friction column. High initial support force can ensure that the pillar is in close contact with the roof, effectively preventing the roof from sinking and improving the support effect.
Uniform bearing capacity
As the Single Hydraulic Prop has the characteristics of high initial support force and constant resistance, all the pillars can bear the load more evenly, reducing the phenomenon of overloading of individual pillars. This is conducive to maintaining the integrity of the roof plate below medium stability and improving the overall stability of the support system.
Fast lifting speed
The lifting speed of the Single Hydraulic Prop is an important indicator of its working efficiency. Through the hydraulic system, the Single Hydraulic Prop can achieve rapid column lifting and lowering, thus shortening the support time and improving work efficiency.
Strong adaptability
Single Hydraulic Props are suitable for different coal seam conditions and support needs. For example, DN internal injection monobloc Single Hydraulic Prop can be used in the gently inclined back mining face with the inclination angle of the coal seam less than 20°, and it can also be used in the back mining face with the inclination angle of 25°~35° after taking certain safety measures. In addition, the working stroke of the Hydraulic Prop is large, which can adapt to the change of the height of the coal seam and provide effective support for the coal seam of different thickness.
