Subsidence observations over shallow workings, including pneumatic stowing and rapidly-advancing facies
Amplitudes of subsidence are analyzed for different packing and stowing systems, both for critical and subcritical areas of extraction; use of maximum slope of subsidence basin as yardstick for comparing intensity of ground movements is suggested; effects of surface movements over rapidly advanced and pneumatically stowed faces; effects of older workings above and below working of seam under large railway viaduct. (See also Min Engr v 120 n 7 Apr 1961 p 552-69; Iron and Coal Trades Rev v 182 n 4843 May 12 1961 p 1013-14)
