Longwall mining productivity in U.S. has been on the increase since its introduction in the 1950's. Productivity gains are resulting from a number of operational and equipment changes. One trend has been an increase in the dimensions of longwall panels. Over the past 5 years, several longwall operations have opted to significantly increase the size of their panels. This paper takes a generalized look at how longwalls are changing in size, how this can impact health and safety, and point out what some current extended longwall operations are doing to improve health and safety.
