Recent Insight into Longwall Strata Movements Deduced from Subsidence Analysis

In this paper, a number of novel hypothesis that provide a fresh perspective on the characterization of strata movements associated with longwall mining are developed by analyzing subsidence measurements with an influence-function-based computer program. With this influence-function technique, easily obtained surface displacements can be used to determine some of the complicated, expensive, and difficult to measure movements of the immediate...
