Since the adoption of the surface mining reclamation and control act of 1977 there has been a sudden rise in demand on guidelines for minimizing surface subsidence and its associated structural damages. A 10-month survey resulted in a collection of surface subsidence surveys that was conducted by coal companies in the northern Appalachian coal field over the past 20 years. This paper presents the preliminary results of the longwall subsidence data.
