Objective
The two main dangers involved in working a retreating face are release of firedamp and spontaneous combustion of coal in the goaf.
Firedamp is produced in varying quantities and at irregular intervals. Despite major advances in ventilation and firedamp drainage, there is still a risk of concentrations above statutory limits occurring. Similarly, although injecting nitrogen into the goaf is an effective method of suppressing heatings, the quantities involved and the injection sites are determined in a fairly empirical fashion.
We need to find out more about the flows of these gases (air, firedamp and nitrogen) in the goaf and, as a result, exchanges with ambient air at the faces. The aim of this project is to devise means of modelling these flows, with a view to controlling them better. It is hoped that finding out more about these phenomena will:
- enable more suitable working methods and sites to be selected to increase drainage efficiency;
- provide more information on areas prone to accumulations of firedamp and improve methods of controlling them,
- optimise and improve suppression of spontaneous combustion by injecting nitrogen.
