Research Activities

The subject matters of research conducted in Mine Ventilation Laboratory are related to unsteady states of gas and air flows in the mine ventilation network.

The currently carried out research encompasses the following areas:

• dynamics of transients of air flow in the mine ducts and workings

• computer simulation of non-stationary process of ventilation as its control factor

• application of the mine monitoring system’s database in the course of ventilation process simulation

• experimental testing of the selected issues relating to flow disturbances in ventilation network

• measurement methodologies and tools for determination of ventilation network parameters and hazards

• testing and calibration of manual and stationary anemometers, that are being applied in mines ventilation and industrial ventilation systems
  

Major achievements

• development of ventilation-oriented software packages VentGraph that may support work of the mine ventilation engineer. Package has been implemented in Polish mines, as well as sold to the Czech Republic, Slovakia and Canada. It is also being used for education purposes at the University of Kentucky, Lexington, USA

• development and implementation of ESCWIN software that cooperates with the mine monitoring system’s sensors, allowing for fire source detection and determination of endangered zone and the staff emergency exit routes

• development and putting into manufacturing process of vane anemometers, both manual and stationary models

• aerodynamic laboratory for anemometers testing

• participation in the comparative research programme for measurement laboratories EUROMET proj. No 388 “Intercomparison of Anemometers”
  

The most important research results

• development of mathematical models that describe unsteady states of gas and air flows in the mine excavations and workings network

• development of mathematical models that describe transient states of propagation of gases generated by fires in the mine workings network

• development of software for numerical simulation of the above-mentioned phenomena for varying conditions of ventilation and with the possibility of testing the impact of inert gases application on the extinguishing process

• development of procedures of fire sources detection, determination of the zone endangered with fire-generated gases flows and the staff emergency exit routes

• development of graphic procedures for the on-screen computer visualization of numerical simulations results. Developed have been also methodologies of drafting schemes of the mine’s ventilation three-dimensional network

• laboratory testing of the pressure and velocity wave propagation, together with verification of developed mathematical models

• trial testing of the fire source dynamics performed in a shaft in CSRG Bytom

• development of measuring-control instruments for recording the rock and gas outburst effects in its immediate neighborhood. With application of this equipment performed was recording of the outburst t course in cross-cut "C" in the Coal Mine "Nowa Ruda"
  

Planned activities

• development of the intelligent software based on data collected by the mine ventilation monitoring system

• development of the new methodologies and instruments for measuring parameters that characterize mine ventilation networks.
