Deformation Mechanism And Prediction And Study On The Surface Of Fushun Power Generation Co.Ltd. By West Open-pit Mining

This article from the actual conditions that the west open-pit mining effect on the surface of Fushun Power Generation Co. Ltd., summarizes the factory surface movement deformation regularity, and aiming at west open-pit mine excavation and factory in place of the special geological environmental conditions, through ADINA numerical simulation analyses surface deformation from 2005 to 2012 and process and mechanism of F1A fault effect caused by the excavation Judge the factory ground deformation trend for the anticipation, and can be good enough to explain the factory strictly F1A rupture due to mining steep open and camp caused as a result of located in its and the nearby industrial buildings, structures and crippling serious destruction and tilt phenomenon. Due to the presence of faults Fl, and played the aggravate F1A fault effect of the function. Finally, based on the factory measured surface subsidence value time series thorough research, introducing chaos theory, through three methods discriminant indicate that the subsidence value time sequence exists chaotic character, creating the Volterra adaptive multi-step forecast model, with C4 point as an example to sink value chaos time series prediction, tested multi-step forecast good performance, predict a satisfactory result.
