Usually, the concrete foundation is not arranged, and the coal base plate is directly used for laying, so the terrain condition is relatively uncontrollable. Under special geological conditions, the head part and the belt storage bin are integrally longer, the driving part is wider, higher requirements are put forward on the installation space, and the situation that the blanking point of the unloading frame is far away from the gate-lane belt conveyor occasionally occurs after the integrated head and the belt storage bin are installed at a section of position which is enough to be accommodated. When the blanking point of the unloading frame is far away from the gate-over adhesive tape machine, the first mode usually adopted is to process a triangular unloading frame or an idle frame body in an emergency manner, mount an unloading roller on the unloading frame, and realize that the unloading mechanism moves forward and drops onto the gate-over adhesive tape machine. The original integrated machine head does not need to bear the unloading function, and a series of parts on the original integrated machine head can only be detached and left unused. The second mode is to add a simple short-distance belt conveyor to make up the distance between the blanking point and the gate-way belt conveyor, so as to play a role of relay, and under the normal operation and start-stop conditions, the relay belt conveyor needs to be matched and followed with a matched belt conveyor after continuous mining to be brought into the operation range of a continuous mining system. This kind of mode needs additionally to increase the short distance sealing-tape machine, needs to link with two sealing-tape machine communications from beginning to end, matches each other and follows, has increased the degree of difficulty that equipment used and maintained.
