When it comes to the bearing capacity of the single hydraulic prop with internal injection in DN, it can be applied to the working face of thin coal seam, medium thick coal seam and thicker coal seam because of the large bearing capacity of the single hydraulic prop with internal injection in DN. Let's explore the carrying capacity of the DN injector single hydraulic prop.
An introduction to the bearing capacity of DN internal injection single hydraulic prop
The DN injection-type single hydraulic prop is a constant-resistance prop, which is suitable for supporting the roof of general mechanized coal mining face in coal mine, and can also be used for comprehensive mechanized coal mining face end support or temporary support. The DN injection-type single hydraulic prop is suitable for roof support and end roof support of coal mining working face. Due to its large bearing capacity, strong anti-deflection capacity, large working stroke and wide range of use, it can be applied to thin coal seam, medium thick coal seam and thicker coal seam working face.
Scope of DN internal injection type single hydraulic prop
1. Dip Angle of coal seam: if the dip Angle of coal seam is less than 20°, it can also be used for the working face with a dip Angle of 25° ~ 35° after taking certain safety measures.
2. 2. Height: not greater than the zui height of the pillar, that is, the zui height of DN18 pillar is 1.8m, and the range of support height is generally 1.3-1.8m; The zui large support height of DN22 pillar is 2.2m, and the range of support height is generally 1.6m ~ 2.2m, etc.
3. The middle of the prop should not be used as the fulcrum of the sliding jack during the bearing process;
4. Measures shall be taken to prevent the surface of the living pillar of the pillar from being broken when it is used in the gun mining face.
