Powered support systems are considered to be backbone of the longwall mining system. A significant development in underground longwall coal mining automation has been achieved with the successful implementation of fiber optics cable for leg pressure monitoring and performance analysis of shield supports. This paper illustrates the development of a continuous monitoring system of roof pressure and support closure with progressive face advance in longwall workings. A case study of a longwall working is illustrated to assess the effectiveness of the monitoring system in assessing the support performance for safer and smooth operation of roof supports in these workings under different geo-mining conditions.
