Application of double packing on longwall roadways
In roadway deformation, first stage of pack compression is followed by disintegration of roof, floor and sides; aim of double packing is to remove localized high stressed region from vicinity of roadway into adjacent region in goaf, by building two parallel packs adjacent to roadway; illustrated description of results obtained in several cases. (See also - n 4406 discussion June 8 p 710-2; Instn Min Engrs -- Trans v 104 pt 10 July 1945 p 512-36, (discussion) 536-46; Iron and Coal Trades Rev v 150 n 4032, 4033, June 8 1945 p 843-8, (discussion) June 15 p 896-7)
