Subsidence development with time — experiences from longwall operations in the Appalachian coalfield
Summary The development of mining subsidence, from the immediate roof to the surface, has a dynamic character and it is related to the progress of underground mining and time. Subsidence prediction methods which can pre-calculate the final and intermediate stages of this process are important in mine design. In this paper a prediction method proposed by Knothe (1953), and based on Gauss distribution of influences and Mitsherlich's ‘law of limited increase’, is presented and applied to determine the subsidence development over time in the Appalachian coalfield. The method has yielded very promising results and it was verified for a number of longwall case studies.
