Computer Modeling of the Surface Effects of Subsidence Control Methods
This paper details the development and application of a system for modeling the effects of subsidence control methods on surface subsidence over longwall coal panels. The term 'subsidence control methods' as used in this paper should be understood to cover coal pillars, packwalls or any backfills used to support the mine roof and to limit the effects of surface subsidence. The work began by choosing an appropriate subsidence predictive method on which to superimpose the effects of different control schemes. Advantages and shortcomings of using this system for predicting the surface effects of subsidence control schemes are discussed and recommendations for future research are given.
