The computer-aided roof activity monitoring systems for longwall mining include the face loading and entry convergence monitoring systems and have been employed at some of the Cyprus Amax`s underground coal mines to continuously record changes in face shield resistance across and entry convergence ahead of the longwall face at any moment during longwall mining. These systems can provide more accurate and representative data for us to study the mechanism of the overburden strata movement above a longwall face and to verify the effectiveness of the current face and entry roof supports. This paper describes the functions of both the face and entry monitoring systems, and discusses our findings and the issues related to the successful control of longwall face and entry roofs.
