The Practical Application of Subsidence Prediction in the Illinois Coal Basin

  • Description:
    The need for predicting mine subsidence derives from the damaging potential of the ground movements. The mining of coal underground can create vertical and horizontal movements at surface level, which are manifested as induced slopes, curvatures and strains. The slopes and strains damage surface or underground features, such as houses and buildings, power lines, pipelines, crops, or aquifers. Under present technological and economic conditions, subsidence prevention above longwall mines is not feasible. Nonetheless, it has been demonstrated, particularly in Europe, that surface subsidence can be predicted and controlled, thereby lessening the adverse effects of ground movements. With a reliable prediction technique available, subsidence can be predicted as part of the mining plan and, if environmentally or economically unacceptable situations are foreseen, remedial measures can be implemented. However, to be useful, the technique must be able to predict all of the components of subsidence as well as the damaging manifestations, i.e., vertical and horizontal movements, slopes, curvatures and strains. This paper presents research, conducted by the Bureau of Mines, on modifying the influence function method to predict subsidence of the ground surface. The application of the technique then is demonstrated for .the prediction of pre-subsidence and post-subsidence shoreline contours around Rend Lake, IL, the prediction of induced slopes as it relates to crop or power line damage, and the prediction of curvature for the estimation of structural damage.
