Abstract

The reasons of hydraulic support not keeping consistency when working underground are analyzed and the influencing factors are got in the mining process. According to the input-output relationship between the influencing factors and the support displacement, we design the hydraulic support straightening system model on the basis of the support vector machines and chaos particle swarm. The model can give the accurate support displacement values for different environments through the simulation and data test, which can achieve the desired goals.
