|The product has almost completely replaced traditional shelf-style stone dust barriers and water trough barriers in Australia and South Africa.||Guidelines have been drawn up for the design installation and maintenance of bag barrier explosion barriers. Advantage has been taken of the greater degree of flexibility and reduced costs of bag barriers to design layouts that reduce labour and production downtime associated with barrier maintenance.
The bag barrier system is proving especially popular in longwall mines as the bags can be put up during gateroad development and left in place for the extraction phase. This eliminates substantial labour requirements and minimises production downtime in relocating the barriers especially during extraction.
