Objective
The purpose of this study was the design, construction and application of an aerodynamic scale model of a modern retreat longwall coal face. The objective of the modelling was to simulate the effects of various parameters on the accumulation of methane gas, and hence to provide information which would be of practical relevance to the control of gas in underground mines.
The principles underlying the model have been defined, the techniques developed and a substantial model constructed, tested and applied.
This involved (i) the development of specifications for how these simulations could be achieved in the small scale and the essential features to be included in the model; (ii) development and testing of ideas for scaling the effects of turbulent dispersion, the formation of gas layers, and flow through the waste; (iii) development of experimental techniques; (iv) construction of models suitable for the experiments and simulations; and (v) application of the model to the investigation of the consequences of various changes in mining conditions, gas emission, ventilation system, etc.
The project was primarily aimed at British mines, but it also included (with support from Charbonnage de France) a study of the feasibility of extending the application of the model and associated techniques to the conditions and issues relevant to the French coal industry.
