Description

The Single Hydraulic Prop is an essential component of a safety support system used in underground coal mines. This innovative constant resistance prop works in conjunction with a steel roof bar to provide reliable support. Its operational mechanism involves a plunger that rises to create an initial supporting force, accommodating varying loads during the mining process. When high-pressure fluid is injected, it pushes a steel ball in the one-way valve, allowing fluid to flow into the prop’s cavity, causing the plunger to rise and secure the roof bar against the working surface. As the coal-cutting area expands and time progresses, the prop adjusts to the increased counterforce, maintaining stability. The built-in relief valve ensures that when the pressure exceeds the rated load, excess fluid is released, allowing the prop to adapt while keeping the load consistent. This unique feature makes the Single Hydraulic Prop a vital asset for ensuring safety in mining operations.
