Abstract: Hydraulic support is the important equipment in coal mining. The progress of hydraulic support equipments is important for the development of coal mining in China. This article starts from the technical composition of hydraulic support equipments and the development of patent application trends，by sorting and analyzing the data of hydraulic support patent applications, then selects the hydraulic support as the research focus, and obtains the technical requirements, efficacy and technology development route of the hydraulic support.Studies show that China's hydraulic support technology should aim to improve efficiency with the reliability, high strength, automation, and large-scale as the development priorities. Especially we should make the control systems as a breakthrough point.
