Objective
With increasing mechanisation, many difficulties are encountered in installing water barriers in mine roadways. These arise partly from the dimensions of the troughs themselves and partly from the limited space available for them because of the roadway configuration. Other factors to be borne in mind are the need to suspend the troughs horizontally, maintenance problems, difficulties arising from high temperatures (evaporation) and mechanical effects liable to cause their destruction.
For all these reasons there was an increasing need to develop water troughs which were not subject to all these disadvantages but were at least equally effective.
Such troughs would have to satisfy the following requirements:
- operation independent of the position of the troughs in the roadway cross-section;
- prevention of evaporation;
- sufficient ruggedness to prevent damage during transport and installation;
- sufficiently rapid release of the suppressant in the event of an explosion to ensure extinction of the flame.
