Visual Simulation Study of Pick Loads on Continuous Miner

Abstract

A continuous miner is one of wall mechanized coal face; its design quality and performance have directly effect on coal productivity and economic benefits. A pick on a continuous miner, contacting with coal and rock, is a tool cutting directly coal and rock, its force condition during it cuts determines directly loads of the cutting mechanism, pick wear and tear, fabric vibration and cutting performance of the machine, is the basis for the design of a continuous miner. By considering a variety of factors, a mathematical model, including the coal and rock properties, structural parameters of a pick, pick sequence, cutting parameters of the continuous miner, is established in the paper, visualization software which can be directly reflected pick' forces on the continuous miner is design. On this basis, pick' forces of a continuous miner under different working conditions are simulated and studied, which create conditions for understanding pick' force during cutting process of a continuous miner, computer-aided design of the cutting mechanism, dynamic design and research of the machine.
