A Method for Evaluating the Stability of Slope Rock Mass

InactiveCN102279421AGeological measurementsComplex dynamic systemsDirect effects
For the combined underground and open-pit mining methods, according to the spatial correspondence of the mining area, some of the two mining influence domains overlap each other, resulting in the interaction and superposition of the mining effects, thus forming a composite dynamic system. Therefore, the slope The deformation mechanism of rock mass is more complex. Underground mining has three effects on the overlying rock mass in the area of ​​influence, that is, the change of the overlying rock layer, the reduction of the overall strength and the change of the stress field in the area of ​​influence. The latter is due to underground excavation changing the stress distribution state of the original rock. Within its influence domain, the stress values ​​and behaviors at different spatial locations are different, so the damage to the overlying rock mass by underground excavation is zonal, and this zonal stress change will occur with subsequent excavation different processes of change. This change process will directly affect the stability state of the slope rock mass, that is, the occurrence of this stress restricts or changes the stability state of the slope mass. Therefore, in the stability analysis of slope rock mass, this main influencing factor should be taken into consideration. However, in the past, when dealing with such problems, the analysis method under the influence of single open-pit mining was approximately applied, and the results were somewhat different from the actual situation; the present invention deduces a slope rock mass stability evaluation on the basis of theoretical analysis Methods to provide scientific basis for the follow-up mining design and safety production of such mines.
