Supporting device for coal mine tunnel crossing fault

The invention discloses a coal mine tunnel fault crossing supporting device, and relates to the field of coal mine supporting and provides a supporting component, the supporting component is used for supporting a coal mine tunnel, connecting components are fixedly connected to the two sides of the bottom of the supporting component, and blocking components are fixedly connected to the two sides of the side face of the supporting component. According to the device, the supporting component is arranged, the support drives the auxiliary mechanism and the blocking plate to abut against the inner wall of a coal mine, so that the inner wall of a coal mine tunnel is supported and protected, the blocking plate slides in the receding groove through the sliding rod, and meanwhile, through the extrusion and stretching effect of the first spring, the blocking plate can slide in the receding groove; when vibration occurs, buffering can be conducted in time, the internal structure of the support is protected, meanwhile, th
