[Abstract] This paper is a retrospective on the development, application and enhancement of the LaModel program from a personal perspective. The narrative starts with an explanation of the objectives behind the original development of the program, and then introduces some of the unique and very practical features of the program. Next, a demonstration of how LaModel was advantageously used to model stresses and displacements in a multiple-seam mining situation with highly variable topography is presented. This is followed by the details of a number of the major enhancements and expansions of the program over the years. An extremely extensive back-analysis of the Crandall Canyon Mine collapse is then briefly presented, along with the associated development of a recommended calibration procedure for the critical input parameters to LaModel. Finally, some of the present research areas are briefly described and a couple of exciting future enhancements are introduced.
