MECHANISM ANALYSIS ON FLEXIBLE AND FOLDED FLOOR LIFT AND STUDY OF ITS CONTROL COUNTERMEASURE
挠曲褶皱性巷道底臌机理分析及防治对策研究

A catastophe model is put forward for analyzing destabilizing mechanism of flexible and folded floor. The zoning of floor stability in control space, influence of the force motion ways in control space on floor stability and the trigger mechanism of vertical force disturbance are probed. The ample and essential condition of deciding destabilizing is set up. On the basis of analyzing the effect of various affecting factors on floor stability, the control countermeasure of this kind of floor lift is also studied by means of FLAC.
