Investigation into profile-cutting control of boom-typed excavators

The excavator is a key equipment for mining.According to different actions upon tunnel sections,the excavator can be categorized into tunneling boom machine and partially-sized tunneling machine.Based on the working procedure of boom-typed excavator EBZ-160,a mathematical model is developed for profile-cutting control.As such,this approach establishes a theoretical basis on excavator automatic control and excavating mechanization.
