A Master Environmental Control and Mine System Design Simulator for Underground Coal Mining. Volume VI. Production Subsystem.

摘要

This report is volume 6of an 11-volume report on a dynamic general purpose computer simulation model for underground coal mining. This volume describes the production subsystem of the Master Design Simulator. This subsystem provides the means for moving the model through time on a computer and recording its behavior. The logic of the production subsystem can accommodate multiple face units and both standard and nonstandard activities in each mining section. Each activity is assigned a specific and separate list of instructions for the simulation. These instructions include determination of tramming paths,wait and change point locations,entry and cut locations,as well as commands to advance in the mining cycle and tram. Advancing through the mining cycle is handled through a sequential execution of a subset of face jobs that is predetermined in the program logic. A case study is presented illustrating the application of the model as a free-standing program. The appendices comprise a user's manual for the subsystem,and include a program listing.
