Development and construction of longwall roadways
Discussion of advancing longwall roads which are driven through areas from which coal seam has been totally extracted; to construct roadway so that it will remain in state of reasonably good repair without undue maintenance, everything possible must be done to bring overlying strata to state of equilibrium as quickly as possible and avoid future disturbance of equilibrium. (See also - discussion p 664-8; Bul n 343 Nov 1940)
