Abstract
This report, Volume 4 of the 11-volume report on the master design simulator (MDS), describes the roof support subsystem. This model is based on popular roof support practices for different geological environments with related restrictions imposed by the Coal Mine Health and Safety Act of 1969. From geological sections, the model determines the anchor horizon for roof bolts and the density of roof support necessary. The roof support subsystem is tied to both the geology and reserves subsystem and the production subsystem of the MDS, but it can also operate as a free-standing model. Several case studies are presented showing the application of the model. A detailed user's manual, including a program listing, is presented in the appendices.
