Study On Large Dip Angle Mining Face Hydraulic Support Based On Inventor And Ansys

The hydraulic support is the key component of coal mining fully mechanized equipment. At present, the current research and using level of our country is in the lead level in the world. However, due to the complicated geological conditions and difficult to guarantee the stability, it has made slow progress on the researches of hydraulic supports which is suitable for fully-mechanized working face with large dip angle. Therefore, taking the project "Research and optimization on fully-mechanized working face hydraulic support with large dip angle" from the company as research background, it is mainly to solve the control technical problem of the support’s stability in this paper. Methods of optimization, simulation, finite element analysis were used and the factors affecting the stability of support have been found to achieve the optimization of support’s design,shorten product design and manufacturing cycle and improve the reliability of support.In this topic, the relationship between hydraulic support and surrounding rock has been researched and the characteristics which the hydraulic support should possess were come up with to provide theory support and analysis basis for the optimization and design. With the support of virtual prototype simulation technology, the FEA model of key parts of the ZZ4200/15/32 hydraulic support has been built and analyzed. Many kinds of load characteristics, relationship between surrounding rocks and design considerations were obtain to further guarantee the safety and stability of the support structure after analyzing and checking the strength of the support under different loading conditions. Effective anti-skid and tilting prevention device has been designed after researching the stability of the supporting cover type hydraulic support. This will lay the theoretical foundation for the design and research of anti-skid and tilting prevention device.
