Research And Design For Fully Mechanized Caving Hydraulic Pressure Support

The comprehensive mechanization of coal mining is the zcceleration coal industrialdevelopment of our country, raises labor productivity substantially, realizes the modern astrategic measure of coal industry. Synthesize mechanization not only output big,efficiency has low cost high and can alleviate heavy physical labor and improvementworking environment, is the technology of coal industry develop direction. Hydraulicsupport is one of the comprehensive most important equipment in the mechanizationmethod of coal mining.Geological conditions according to the sand mines Fengfeng Group of a fullymechanized caving coal seam, the matching equipment of shearer and scraper conveyor isestablished, according to the "three machine" requirement, the design of the cavinghydraulic support. In accordance with the requirements of the selection of caving coalhydraulic support, were studied from determining mechanism type selection, overalldesign, linkage and determine the beam size etc.. For fully mechanized working face,studied the design of working face roof caving coal hydraulic support in the middle, themain structure and technical characteristics of the determined, to support the forceparameters of dynamic analysis, visualization, to ensure that the design meets therequirements; and the working face crossing hydraulic support for the study design,determine the structure and technical features. Finally, the hydraulic control system isdesigned, with the adjacent control mode, makes the operation more convenient and safe,to realize essential safety production. Therefore, this research has important practicalsignificance in fully mechanized top coal caving mining.
