Ohio Automation specializes in Mine Planning Software for underground mines called ICAMPS (Integrated Computer Aided Mine planning Software). We have MineSimU for mine planning that produces timing maps, tonnage reports, and much more. MineVent and MineVent 3D for mine ventilation software. MineWater to simulate water flow systems. Finally MineFire for mine ventilation in real-time to simulate what happens if a fire occurs or even if other changes occur while simulation. All of our products run inside of AutoCAD (2010 and above) so that you have the full power of AutoCAD commands at your disposal.

MineVent and MineVent 3D

Our most popular product is MineVent. MineVent and MineVent 3D are mining ventilation software modules that simulate the airflows (cfm) through the airways and pressures (inches H2O) at the nodes. It uses an enhanced version of the Hardy Cross Method and a second more robust engine called the Gradient Method for calculations. The program can use the actual mine map to draw the ventilation network and then use the actual branch lengths to calculate resistances using one of 10 formulas or you can enter the resistance by hand. It has special formulas for leakage branches and regulators and calculates the regulator openings. The above schematic is not any realistic mine map it is just a sample that shows how user defined branch codes (Intake, return, leak or whatever you want to name them) can have different colors and abide on different layers. It has many modification and output features. Modification features include moving and stretching branches, globally changing the branch parameters such as resistances, editing branches graphically and in list format, export to spreadsheet and more. Some of the more popular output features are List Compare to comparing the results of the last two runs to see what effects a change has on the ventilation network, Listing quantities, pressures, pressure drops, negative quantities, regulators and branch cost. The output includes the fan cost. Graphically you can draw the quantities and pressures on the network at any sizes you prefer, draw gas flow percent, color the network by parameters. MineVent supports Imperial and SI units.

  • Ohio Automation is very responsive to request for new features/enhancements/improvements

MineFire 3D

MineFire is also mine ventilation software that runs inside of AutoCAD. MineFire has a easy to use graphical user interface to the former U.S. Bureau of Mines MFIRE version 2.20 expanded upon and improved by NIOSH to include real-time modifications, now called MFIRE 3.0.

The difference between MineVent and MineFire is that it requires more input, has more output, runs in real-time so that you can make changes while it is running or in a time table before running and it has 3 phases: Steady State, Non-Steady State and the Quasi-Equilibrium. In theory the Steady State should yield results similar to MineVent. However, MineVent is much better for Steady State ventilation and likely more accurate. MineFire can also be used to simulate ventilation networks changes such as resistance change, temperature, fan changes in real-time.

MineWater is used to simulate the flow of water through complex piping systems. It is much like MineVent and has some of the same menu options and it is water instead of air. It is also similar to MineFire as it works over time as water flows through the mine so you can step through to see if a tank is empty or what the water flow (gpm) and pressures are in each pipe and node as you go through pre-determined time steps. The nodes are different they can be either a Junction where pipes join or characteristics change, a Source which is an inflow into the system, or a Sump which is a storage tank.
