Method of building strip packs in goaf and allowing roof to collapse and fill cavity; study of both methods at Kirkby Colliery; description of tests and face conditions; firedamp emission; where natural conditions and unsuitable packing material make it impossible to build substantial packs capable of supporting rear abutment load and cantilever weight of nether roof bed, roof control may be improved by total caving.
