Asymmetric coordinated support device for gob side entry based on combination of flexibility and rigidity

An asymmetric coordinated support device for gob side entry based on combination of flexibility and rigidity, comprising an inner support board (3), an outer roadway side support assembly (7), an outer roof support assembly (8) and a flexible reinforcement layer (5), wherein the inner support board (3) is supported to an innermost side closest to a rock layer to be supported (2) in an extending direction of a roadway;

• a side of the inner support board remote from the rock layer is provided with the outer roadway side support assembly (7) extending along the direction of the roadway and the outer roof support assembly (8) located on a roof of the outer roadway side support assembly;
• characterized in that,
• the flexible reinforcement layer (5) is provided between the outer roadway side support assembly (7) and the inner support board (3), and the outer roof support assembly (8) and the inner support board (3);
• the flexible reinforcement layer (5) includes a plurality of sets of flexible micro-slip assemblies (9) and solidified reinforcement layers (15), wherein each flexible micro-slip assembly (9) is disposed between the outer roadway side support assembly (7) and the inner support board (3) or between the outer roof support assembly (8) and the inner support board (3) in an inclined manner with a certain inclination angle to a horizontal direction;
• each flexible micro-slip assembly (9) is inclined in a direction and has an inclined extension direction;
• two sets of flexible micro-slip assemblies (9) that are up and down or horizontally adjacent are inclined in opposite directions;
• each solidification reinforcement layer (15) is filled in a flexible reinforcement cavity configured by the flexible micro-slip assembly (9), the outer roadway side support assembly (7), the outer top support assembly (8) and the inner support board (3);
• each flexible micro-slip assembly (9) is capable of micro-slip along its inclined extension direction, and in the case of micro-slip, a horizontal slipping force and a vertical slipping force act on the outer roadway side support assembly (7), the outer roof support assembly (8) or the inner support board (3);
• and
• each flexible micro-slip assembly (9) includes an upper flexible support seat (10), a lower flexible support seat (11) and a vertical component seat (12), wherein the upper flexible support seat (10) extends in an inclined direction and is disposed between the outer roadway side support assembly (7) or the outer roof support assembly (8) and the inner support board (3);
• a lower portion of the upper flexible support seat is abutted with the lower flexible support seat (11) provided in the same direction as the extension thereof, and a central portion of the lower flexible support seat is provided with a through hole;
• a roof of the vertical component seat is integrally fixedly connected below the upper flexible support seat, and the vertical component seat (12) is disposed downward through the through hole.
