Study on Large Inclined Angle Integrated Caving Hydraulic Support Stability Control

Abstract:

Analyzed the main factors of affecting hydraulic support stability, this paper analyses anti-topple and antiskid technology to apply to inclined angle 15~33°and compatible supports ZF4200/16/26. Through the practical application in shanjia mine, it can meet large inclined angle mine demands. The follows were studied that can influence the stability of support in large inclined angle coal seam. Every roof situation in the direction of large inclined angle suffering different stress lead to different caving property, and the roof motivation can affect other supports strained condition and stability. Caving mechanism behind the caving coal support suffer downward force, and the force is put on caving shield and tail beam, so it makes supports generate angle of bank. The support would lose its stability with working face processing and supports advancing for descending support and losing point of support.
