Some problems of shaft inset and inset extension roadway construction at Abernant colliery
Effect of heavy pressures on inset supports in reinforced concrete, on inset extensions lined with either brick sidewalls and roof girders or reinforced concrete and form of repair carried out on pit-bottom roadways; in plastic type of strata encountered at Abernant good method of constructing permanent roadways is to pilot and then enlarge; strata affected by drivage of 14 ft roadways in solid extended to 15 ft on either side.
