• MULSIM/NL Theoretical and Programmer's Manual
  1/1/1992 - Information Circulars
  The program described in this U.S. Bureau of Mines report is part of the MULSIM/NL package, which features the actual BEM program described herein, as well as a preprocessor program called MULPRE/NL and a plotting postprocessor program called MULPLT/NL.
• Probability of Making a Successful Mine Escape While Wearing a Self-Contained Self-Rescuer - A Computer Simulation
  1/1/1990 - Reports of Investigations
  In an effort to estimate the chances of a miner making a successful escape while wearing a self-contained self rescuer (SCSR), a computer simulation was developed.
• Physiological Responses and Subjective Discomfort of Simulated Whole-Body Vibration From a Mobile Underground Mining Machine
  10/1/1988 - Conference papers
  Eight men participated in a pilot study to evaluate the effects of shock and whole-body vibration (WBV) on heart rate (HR), blood pressure (BP), and subjective discomfort.
• Evaluation of Mine Illumination Systems Using Numerical Modeling
  10/1/1978 - Conference papers
  The analysis of a machine-luminaire configuration is well suited to computer analysis; the incident light levels can be calculated at the required set of points. This paper presents a description of the techniques involved in this simulation.
• Study of Mine Fires and Mine Ventilation: Part I, Computer Simulation of Ventilation Systems Under the Influence of Mine Fires
  9/1/1977 - Contract reports, Open File Reports
  An existing computer program for mine ventilation network is modified so that it can simulate ventilation conditions under the influence of mine fires. The resulting new program is designed for the practical ventilation engineer and should be applicable...
• Two-Phase Flow in Coalbeds
  1/1/1975 - Reports of Investigations
  This report reviews experimental evidence indicating a relative permeability effect that causes the flow of methane to increase with time when a coalbed is degassed by boreholes.
• Research and Development Contract for Coal Mine Communication System: Volume 3 - Theoretical Data Base
  11/1/1974 - Contract reports
  Eight coal mines were visited to determine their communications usage and requirements. Available equipment was surveyed and evaluated to determine its applicability to the needs of the mines. Volume 3 contains all information used in predicting the per...
• MFIRE Users Manual Version 2.20
  8/1/1995 - Unpublished documents and reports
  MFIRE is a computer simulation program that performs normal ventilation network planning calculations, and dynamic transient state simulation of ventilation networks under a variety of conditions. This user manual describes the development of MFIRE, the...
