    May 26, 2017 Pillar extraction with continuous miners poses a risk of loss of roof control in the immediate working area or extracted area ( goaf ) resulting in the continuous miners and even the operators being buried. The development of mobile roof supports ( breaker line supports or BLS's ), has largely ameliorated this risk, but the safe application
