Application of signal processing technology for automatic underground coal mining machinery

This paper reports on an industrial application of modern signal processing technology in the development of a new automatic conveyor and bolting machine for underground coal mining. The machine is of special interest to the mining industry as it improves mine personnel safety as well as increasing the efficiency of roadway construction. We show how real-time signal processing component technologies are needed to overcome a range of sensing, monitoring, control, and navigational challenges. We also highlight some of the important practical issues associated with the deployment of intelligent processing systems in coal mining contexts. 1
