Single Hydraulic Prop for Temporary Support: Features and Applications

The single hydraulic prop for temporary support is a core temporary supporting device widely used in underground engineering fields such as coal mining and tunnel construction. It relies on hydraulic pressure to realize lifting and load-bearing, and its design and performance are tailored to the needs of temporary support scenarios.

1. Core Features

  • High Load-Bearing Capacity: Equipped with a reliable hydraulic system, it can provide stable supporting force (usually ranging from tens to hundreds of kilonewtons) to resist the pressure of surrounding rock and soil layers, effectively preventing roof collapse or wall deformation in temporary working spaces.

  • Adjustable Height: The prop’s length can be flexibly adjusted through hydraulic expansion (with adjustable ranges varying by model, commonly from 1 meter to over 3 meters). This adaptability allows it to fit different heights of temporary working faces, eliminating the need for customized cutting of supporting components.

  • Quick Installation & Dismantling: Compared with fixed steel supports or concrete props, it has a simple structure—consisting of a cylinder barrel, piston rod, and control valve. Workers can complete installation or dismantling in minutes using matching hydraulic tools, significantly improving the efficiency of temporary support setup and withdrawal.

  • Good Stability & Safety: The hydraulic system is equipped with a one-way valve and pressure relief protection device. It can maintain a stable supporting state for a long time without gradual settlement, and automatically release pressure when the load exceeds the safety limit to avoid prop damage or safety accidents caused by overloading.

  • Relatively Light Weight: Compared with traditional solid steel props of the same load-bearing level, its hollow cylinder structure reduces overall weight (most models weigh less than 50 kg), making it easier to carry and move in narrow underground spaces or temporary construction sites.

2. Main Applications

  • Underground Coal Mining: It is widely used in temporary working faces such as coal mining roadways, fully mechanized mining face advance supports, and temporary repair zones. It provides temporary support for the roof above the working area to ensure the safety of miners and mining equipment during coal extraction or roadway maintenance.

  • Tunnel & Subway Construction: In the excavation stage of tunnels (such as highway tunnels, railway tunnels) or subway stations, it is used to support the newly excavated tunnel roof or side walls before permanent lining (e.g., concrete spraying or segment assembly). This prevents rockfall during the interval between excavation and permanent support.

  • Temporary Excavation Projects: For above-ground or shallow underground temporary excavation works—such as foundation pit support for building construction, pipeline laying trenches, or temporary cave excavations—it serves as a movable supporting component. It can be quickly deployed and adjusted according to the excavation depth and scope, and recycled after the project is completed.

  • Emergency Rescue Scenarios: In emergency situations such as mine collapses, tunnel accidents, or building structure damage, it can be used as a temporary emergency support tool. It helps prop up unstable structures (e.g., collapsed roof fragments, tilted walls) to create a safe rescue channel for rescuers and trapped personnel.
