Mechanical analysis and kinematic simulation of a hydraulic support used in backfilling and the coal mining face
Abstract：A mechanical model was constructed to analyze the mechanics of the top beam and three rows of columns of a new type hydraulic support. Pro/E software code was then used to simulate the three dimensional model and estimate its kinematic properties. Movement in the main components of the support was simulated and curves relating movement to stress were ob- tained. These analyses were used to design the ZZC8800/20/38 hydraulic support with front legs or tail legs, having respectively 4.1 or 4.6 times the power of the middle legs. This design has safely been applied to one coal face in the Pingdingshan XII mine. The application verified the practicality of this particular design.
