2) When moving the rack, slowly supply the liquid to move the rack. If it is difficult to move, immediately stop moving the rack, and move the rack only after finding out the reason and handling it.3) If the mining height is insufficient or the top wall is broken, the top wall should be handled first, and then the frame can be moved. Before moving the frame, observe the surrounding roof and coal sides.4) working face local help off the top or front end of the guard help plate is more than 800mm away from the working face coal wall, should move ahead of frame in time, realize the advance support of roof.5) stent in the presence of run, run, leak, channeling liquid, need to be handled in a timely manner. When handling the support, it is strictly prohibited to have single leg pin, wire consignment and no pin.6) When lifting the bracket, the front beam should be prevented from carrying the lifting bracket to prevent the pin from breaking and hurting people.7) After the support is moved, the side guard plate shall be used to coordinate the spacing between the supports. After the support is raised, the telescopic beam shall be extended in time and the guard plate shall be tightened to close the coal wall.
