The U.S. Bureau of Mines is actively involved in the development of intelligent machine control technology for the U.S. mining industry. Significant increases in worker safety and productivity should result from this research, which will enhance U.S. competitiveness in world markets, as well as help reduce coal-related energy costs domestically. One of the most critical elements associated with autonomous underground coal mining is the development of an appropriate coal interface detection (cid) horizon control system that will allow a mining machine to automatically track a coal seam and extract only coal. Several promising cid techniques are currently being investigated by the Bureau. These include machine vibration and adaptive signal discrimination, natural gamma radiation, thermography, x-ray fluorescence, and radar. This paper provides a brief overview of some of the current cid research work that the Bureau is conducting.
