What Is A Hydraulic Support?
A hydraulic support, also known as a powered roof support or shield, is the structural backbone of a modern underground longwall mining system.
As a key component of the “four machines and one support” system (shearer, scraper conveyor, transfer conveyor, and hydraulic support) in fully mechanized mining, it plays an irreplaceable role in ensuring mining safety, improving production efficiency, and promoting intelligent mining transformation.
Powered by high-pressure emulsion, hydraulic supports realize a series of automatic actions such as lifting, lowering, moving, and conveyor pushing through the expansion and contraction of hydraulic cylinders. Its core function is to provide timely and reliable support for the roof of the mining face, preventing roof collapse, gangue falling, and coal wall spalling, thus creating a safe and stable working space for mining equipment and operators.
Key Components of Hydraulic Supports
A standard hydraulic support is composed of two core parts: the steel structure and the hydraulic system, supplemented by auxiliary components to ensure comprehensive performance:
Auxiliary components: Such as spray systems (dust reduction and cooling), anti-skid and anti-toppling devices (for steeply inclined working faces), and coal wall protection jacks (preventing coal wall spalling).
Steel structure (load-bearing main body): Including top beam (directly contacting the roof to transmit supporting force), shield beam (protecting the internal space from gangue intrusion), base (supporting the entire support and transmitting pressure to the floor), link mechanism (ensuring vertical support and preventing tilting), and side guard plate (preventing gangue from entering between adjacent supports).
Hydraulic system (power execution unit): Consisting of columns (core load-bearing hydraulic cylinders determining supporting height and force), pushing jacks (realizing support moving and conveyor pushing), balance jacks (adjusting the angle between top beam and shield beam), control valve group (the “control center” regulating the action of each cylinder), and pipeline system (connecting the pump station and cylinders to transmit high-pressure emulsion).
Wide Application of Hydraulic Supports
Our hydraulic supports are engineered with modular flexibility and specialized designs to cover the full spectrum of modern underground mining conditions.
From thin seams in difficult terrain to world-record height requirements, our equipment is successfully operating in the following scenarios:
1. Core Application Scenario: Underground Fully Mechanized Coal Mining Faces
The primary application scenario of hydraulic supports is underground fully mechanized coal mining faces, which are the core part of modern coal production. In these faces, hydraulic supports form a closed protective system with shearers, scraper conveyors, and other equipment, realizing the integration of coal cutting, support, and transportation.
Whether it is a large-scale mine with annual output exceeding 10 million tons or a medium-sized mine with moderate production scale, hydraulic supports are indispensable core equipment.
2. Adaptation to Diverse Geological and Mining Conditions
One of the key manifestations of the wide application of hydraulic supports is their strong adaptability to diverse geological and mining conditions. Through customized design and structural optimization, hydraulic supports can be tailored to different coal seam characteristics and underground environments, expanding their application boundaries:
Coal seam thickness adaptation: For thin coal seams (support height < 1.3m), medium-thick coal seams (1.3m – 3.5m), thick coal seams (3.5m – 5m), and extra-thick coal seams (＞8m), there are corresponding thin-seam hydraulic supports, medium-thick seam hydraulic supports, large mining height hydraulic supports, and top-coal caving hydraulic supports. For example, large mining height hydraulic supports with a maximum support height of more than 8 meters are widely used in extra-thick coal seam mining projects, realizing one-time full-height mining.
Roof condition adaptation: Aiming at stable roofs, broken roofs, and soft roofs, different types of hydraulic supports such as chock-type, shield-type, and chock-shield-type are developed. Shield-type hydraulic supports with strong protective performance are widely used in faces with broken roofs and easy coal wall spalling, while chock-type hydraulic supports with large supporting force are suitable for faces with stable roofs.
Inclination angle adaptation: For gently inclined coal seams (inclination angle ≤ 15°), inclined coal seams (15° – 35°), and steeply inclined coal seams (＞35°), hydraulic supports are equipped with anti-skid and anti-toppling devices, side guard plate reinforcement, and other structural designs. Steeply inclined hydraulic supports can maintain stable operation even in faces with an inclination angle of more than 45°, ensuring safe mining in complex inclined environments.
3. Special Tunneling & Roadway Applications
Beyond the main working face, CSTMG provides critical support for the tunnel infrastructure:
Gob-Side Entry Retaining: High-tech supports designed to hold the roof along the edge of the mined-out area (gob), allowing the tunnel to be reused for the next mining panel. This maximizes resource recovery and reduces tunnel excavation costs.
Advanced Roadway Support: Mobile temporary support units for the gate roads (tunnels) ahead of the advancing face, replacing traditional single props for better speed and safety.
4. Expansion to Special Mining Fields
With the continuous advancement of technology, the application of CSTMG hydraulic supports has gradually expanded to special mining fields beyond traditional coal mining:
- in the mining of coalbed methane, hydraulic supports provide stable support for the drilling and extraction working faces, ensuring the safety of extraction operations;
- in the mining of non-coal minerals such as phosphate rock and iron ore with similar underground mining conditions, hydraulic supports are also used for roof support, realizing the cross-industry application of this technology.
In addition, in the renovation of old mines and the mining of residual coal resources, hydraulic supports with flexible movement and strong adaptability play an important role in improving the utilization rate of coal resources.
Hydraulic Support Working Principle
The working process of hydraulic supports is driven by the hydraulic system, which mainly includes four basic actions:
Pushing the conveyor: While moving the support, the scraper conveyor is synchronously pushed forward to keep it closely aligned with the shearer, ensuring the continuity of the coal mining and transportation process.
Lifting the support: The hydraulic cylinder extends to push the top beam of the support to closely fit the roof, exerting a stable supporting force to balance the pressure of the overlying rock and ensure roof stability.
Lowering the support: The hydraulic cylinder retracts to make the top beam separate from the roof, creating space for the support to move forward.
Moving the support: Relying on the pushing hydraulic cylinder, the entire support is moved forward to the new mining position, following the mining progress of the shearer.
