At the Lake Lynn Experimental Mine in the USA the bag barriers were tested in a number of configurations in a multiple heading mine layout, the first time that an explosion barrier has been tested in this way
The area of the mine used for explosion testing of the Bag Barriers consisted of three headings joined by seven cut-throughs
Testing commenced with a Base Case Explosion where the flame extension was measured. Subsequent tests measured the reduction in flame extension as the more barriers were installed in various configurations. This test work has been comprehensively documented by CSIR and SkillPro.
