Abstract

The invention discloses a mounting method of a hydraulic support of a fully mechanized coal mining face. The mounting method comprises the following steps of (S1) tunneling a tunnel between a transportation roadway and a ventilation roadway along a coal bed, disassembling a ground support while enabling the support to descend a well to reach the bottom of a well and assembling the support on a yard connection tunnel under a track of the coal mining face; (S2) performing open-off cut by using a fully mechanized coal mining machine and conveying the hydraulic support to space formed by an open-off cut opening and the tunnel through a conveyer along an open-off cut direction; (S3) enabling a forklift to enter the space formed by the open-off cut opening and the tunnel from the other side of the tunnel and adjusting the position of the support to a mounting position; (S4) connecting a liquid feeding tube and raising the support to a position where the support is distant from a roof by 200mm; and (S5) repeating the step (S2), the step (S3) and the step (S4) until assembling of the support is finished thoroughly. By the mounting method, empty-support time of the roof of the coal mining face is shortened, the safety factor is improved, possibility of heaving floor caused by long mounting time of the coal mining face is reduced, and labor input is reduced. Compared with the traditional mounting method, the mounting method has the advantage that the time and the cost are saved.
