In the longwall coal mining face of the coal mine, the single hydraulic pillar is often used in conjunction with the roof beam to provide temporary or long-term support to the roof. For example, in the blasting face, when the coal is discharged, a single hydraulic pillar needs to be quickly erected under the newly exposed roof to prevent the roof from collapsing and injuring people, and to ensure the safety and orderly progress of the coal mining work. Moreover, with the advancement of the working face, the single hydraulic pillar can also be continuously moved to a suitable position to continue to support and adapt to the needs of the coal mining operation cycle.
