Scope of application

1. It can mine the whole height at once for thick coal layers, large working resistance and large coefficient of expansion.

2. The reinforcement can adapt to the roof with strong pressure, and the roof management effect is excellent.

3. The reinforcement adopts electrohydraulic control system, which can carry out automatic tracking, consistent frame displacement and remote control, and can meet the needs of intelligent and automated coal mining in slaughter.

Constructive features

1. Four-column shielded hydraulic support has 1.75m axle spacing, large working resistance and large telescopic coefficient, and the maximum working resistance can reach 20000-24000kN;

2. The support can use the working surface inclination angle of about 15°;

3. The front and rear support columns are highly reliable double telescopic columns with cylinder diameter φ400mm, and the fastening form adopts the design of outer clamping plate;

4. The support adopts steep shielding beam and short four-axis design to increase the support tilt angle and reduce the area of the rear blank rock, thereby enhancing the safety, reliability and adaptability of the support.
