Book excerpt: This report identifies, reviews and evaluates all the numericalmodeling techniques which have been used for subsidence researchand assesses their practical application for the prediction ofsubsidence over the coalfields of Cape Breton. The study alsoanalyzes a hypothetical case history which is typical of theSydney coalfield using a number of different numerical methods.Based on the analyses and the literature review, recommendationsare made regarding which methods are most appropriate forpredicting subsidence and what methods might become availablewith further development.

Available in PDF, EPUB and Kindle. Book excerpt: Mining subsidence engineering is one of the most important topics in relation to coal mining. Although its occurrence, prediction and control are well known, this project will apply various innovative techniques to an old problem (photogrammetry, InSAR, GPS, seismic tools, SFS). Geology is a major factor in surface subsidence. Empirical predictions are inaccurate where experience is lacking and geology unusual. Geomechanical subsidence modelling can account for geology but requires anisotropic solutions to reproduce subsidence profiles. Four items have been developed in relation to the prediction of subsidence caused by underground infrastructures: two in relation to shafts (telemetry and instrumentation for fill stability, and the laser-scanner techniques for surveys); another in relation to a survey methodology using numerical modelling for infrastructure roadway, and the last one in relation to the effect of mine water on concrete and other materials. A 4D database, called GeoMond-DB has been developed to manage subsidence hazards on the surface, working with data from Germany, Poland and Spain. A methodology based on geomechanical models to establish a prevision of surface and subsidence was carried out and validated. Specially, the consistency of FLAC 3D was checked to evaluate subsidence and the tensile strain on the surface. In conclusion, the techniques employed in this research represent a significant advance on the current situation in forecasting and control of subsidence. Therefore, although some of the investigated techniques must still be refined, it can be said that the results of this research project will have a positive effect in the monitoring of the subsidence in the coal basins of the EU and some outcomes, such as the technique of monitoring the movements of the ground with a GPS and vibrating sensors, could be exported outside the EU.

Book excerpt: In this study, subsidence analyses were carried out for panels B14, B12, B10, B02, C12, C10, C08 of Çayýrhan Lignite Mine using in-situ subsidence measurements. Using the measurements from stations, installed both parallel and perpendicular to panel-advance direction, subsidence profiles were plotted as a function of time and distance from panel center. Horizontal displacement and strain curves were also plotted and compared with subsidence profiles. There are various methods used for subsidence prediction. In this study however, a subsidence model was developed based on empirical model obtained from nonlinear regression analysis. During the analyses SPSS (V.10.0) software was used and the unknown parameters associated with subsidence function were determined for the stations above B14 panel. Since it was too complicated to take all the affecting factors into consideration, only the parameters which could be estimated by statistical evaluation were taken into account during analyses. One significant contribution of this study to subsidence subject was the comparison of the subsidence values measured during this investigation with the values predicted by some other empirical methods. In this study, the structural damages to the pylons installed on ground surface above retreating longwall panels were also investigated by the use of previous studies. Slope as well as horizontal strain changes caused by ground movements due to underground mining were determined. Last but not least, it should be stated another significant contribution of this study to engineering was the collection of a significant database obtained from field measurements.
Download or read book Surface Subsidence Engineering written by Syd Peng and published by CSIRO PUBLISHING. This book was released on 2020-09-01 with total page 402 pages. Available in PDF, EPUB and Kindle. Book excerpt: Underground coal mining disturbs both the overburden strata and the immediate floor strata. The subject of surface subsidence deals with the issues associated with the movement of overburden strata, which are the layers from the seam to the surface, where structures and water resources important to human activities are located. Surface Subsidence Engineering provides comprehensive coverage of the major issues associated with surface subsidence. The chapters are written by experts on surface subsidence in the three leading coal producing and consuming countries in the world: Australia, China and the United States. They discuss general features and terminologies, subsidence prediction, subsidence measurement techniques, subsidence impact on water bodies, subsidence damage, mitigation and control, and subsidence on abandoned coal mines. In addition, the final chapter addresses some of the unique features of surface subsidence found in Australian coal mines. The book provides information on coal seams ranging from flat to gently inclined to steep to ultra-steep seams. Written for mining engineers, geotechnical engineers and students of mining engineering, this book covers both theories and practices of surface subsidence. Unlike previous publications, it also deals with the subsidence impact on surface and groundwater bodies, crucial resources that are often neglected by subsidence researchers.
