A joint research program between the U.S. Bureau of Mines and Cyprus- Yampa Valley Coal Company is being conducted at the Foidel Creek Mine, Oak Creek, Colorado. This program goal is to study the effects of state- of-the-art, high-speed, automated longwall mining on health and safety, and primarily ground stability, under various geological conditions. The Bureau installed an automated data monitoring system known as the ground control management system (GCMS), to monitor in real time the effect of rapid mining on pillar and face loading, stress redistribution in and around the longwall panel, and caving characteristics of the roof. The Bureau's GCMS, combined with the company's existing monitoring systems, which include environmental monitoring, a computer-programmable conveyor belt system, and gamma ray roof control thickness indicators, has been effectively used to improve safety at the face, increase productivity, and reduce production costs.
