The application of hydraulic support in coal mining face of increasing production and raise labor productivity, reduce costs, reduce manual workers and to ensure safety in production is indispensable for effective measures to, Therefore the design of hydraulic support is technically advanced and economically rational, safe and reliable is the main manifestation of the comprehensive mechanization and automation of mining. Hydraulic system as the transmission of hydraulic supports, from a different number of component jacks. Hydraulic systems through the control valve can be manipulated to achieve a variety of hydraulic support action. It has the following characteristics: the use of relatively simple structure, equipment, small size, can be a big long-distance transmission of energy; can bear larger load; the transmission mechanism is not complicated; explosion hazard in the air and dust to ensure safety at work; rapid action; operation, simple conditioning; overload protection and a simple damage. As a working face of the support equipment, powered support the frame type, structure and related parameters, with the working face to the top, bottom conditions and the coal seam adapte
