The invention provides a sliding type flexible advanced supporting mechanism and method. The mechanism comprises a flexible supporting assembly and a walking supporting assembly. The flexible supporting assembly is mounted above the walking supporting assembly. The method includes the steps that in an initial state, the flexible supporting assembly top-braces a roadway top plate in a self-adaptivemanner, and the walking supporting assembly top-braces a roadway bottom plate; when forward moving is needed, an auxiliary supporting longitudinal beam combination of the flexible supporting assemblydisengages from the roadway top plate, an auxiliary supporting cross beam combination of the walking supporting assembly disengages from the roadway bottom plate, hydraulic cylinders are pushed to stretch out forwards, the auxiliary supporting longitudinal / cross beam combination overall moves forwards by one step pitch, and top-bracing of the auxiliary supporting longitudinal / cross beam combination to a roadway is restored after moving is completed; when forward moving needs to continue, a main supporting longitudinal / cross beam combination disengages from the roadway top / bottom plate, the hydraulic cylinders are pushed to retract, the main supporting longitudinal / cross beam combination overall moves forwards by one step pitch, and top-bracing of the main supporting longitudinal / cross beam combination to the roadway is restored after moving is completed; and sliding moving supporting continues to be alternated.
Description
technical field [0001] The invention belongs to the technical field of roadway support, and in particular relates to a sliding type flexible advance support mechanism and method. Background technique [0002] Underground mining is the main form of coal production in my country, and mine roof support is an important safety construction point for underground mining production. When advanced support is applied to the fully mechanized excavation face, it can effectively cooperate with roadheaders, bolters and other equipment to achieve The excavation support anchor runs synchronously, thereby ensuring the continuous operation of the roadheader. [0003] However, due to the soft coal side, broken roof, abscission layer, abnormal development of cracks and other conditions in the roadway, if the excavation workers operate improperly, the roadheader will over-excavate or under-excavate, which will lead to uneven roadway roof and relatively small Large undulations, and the existing a...
