Prediction And Display Of Underground Mine Environments With Microprocessor Technology

This paper discusses recent technology dealing with the use of computer graphics in the mining industry. It presents a newly developed computer software package specifically designed for use in underground mining operations. This software package, developed under a US Bureau of Mines contract, 1) displays mine ventilation schematics and other representative illustrations for a real time data acquisition system and 2) uses the Bureau-owned Minefire and Ventilation Code for display of ventilation and contamination predictions on the microprocessor system. The package uses a unique system of display indexing that provides a simple yet efficient method of recalling a series of mine schematics detailing an underground operation and an alarm acknowledgment scheme that provides an effective method of identifying problem areas that may exist in the mine network. The package was written in Fortran for a 64-kilobyte, Z80-based microprocessor computer.
