The objective of this research was to develop a computer model of subsidence prediction based on the zone area method. This technique was chosen because of its potential to investigate a mining plan of any shape, thus facilitating subsidence prediction over longwall as well as room-and-pillar coal mining systems. A comprehensive subsidence data bank was established that included published as well as unpublished information on subsidence measurements. Based on these studies, some fundamental characteristics of longwall subsidence were established, and this information was utilized to develop an empirical prediction method. The results and comparisons of the study demonstrated that the zone area method has considerable potential for accurate, rational, and flexible subsidence predictions.
