A Master Environmental Control and Mine System Design Simulator for Underground Coal Mining. Volume IX. Water Generator.

摘要

This report is volume 9of an 11-volume report on a dynamic general purpose computer simulation model for underground coal mining. This volume describes the water generator subsystem of the Master Design Simulator. This subsystem simulates the flow of water through a typical watershed-reservoir combination to predict mine drainage quantities in underground workings. The model is an integrated one that handles both the unsaturated and the saturated flow domains as a unified system. The solution of the model is achieved by numerical techniques of finite difference method coupled with finite elements analysis. The water generator can be operated either as a free-standing model or in connection with the geology and reserves subsystem as a part of the Master Design Simulator. A case study is including illustrating the application of the model to actual data. The appendices of the report constitute a user's manual for the program,and include a program listing.
