This paper took the Fengmaoding slope, typically found in the mountainous areas of central Shanxi province, as its research area. The stratum structure of the Fengmaoding slope is a typical coal measures stratum covered by a layer of loess. There are communication towers on the slope mass and top of the slope; railways, roads, and rivers at the foot of the slope. There are many villages across from the slope, therefore, the buildings and structures nearby, even the lives of the villagers are threatened by the damages caused by the deformation of the slope. Tectonic development and mining activities have very profound effects on the stability of the slope. Considering the above, this paper analyzed the effects of the fault in controlling the deformation features of the destabilized slope during underground mining by adopting the method of numerical simulation from these perspectives including displacement, stress, strain, among others. under different circumstances (the faulted and unfaulted) so as to provide guidance for future studies about landslides of the same type and give preventive proposals for reference.
Este documento tomó la pendiente de Fengmaoding, que generalmente se encuentra en las áreas montañosas de la provincia central de Shanxi, como su área de investigación. La estructura del estrato de la pendiente de Fengmaoding es un estrato típico de medidas de carbón cubierto por una capa de loess. Hay torres de comunicación en la masa de la pendiente y en la parte superior de la pendiente; ferrocarriles, carreteras y ríos al pie de la pendiente. Hay muchos pueblos al otro lado de la pendiente, por lo tanto, los edificios y estructuras cercanas, e incluso la vida de los aldeanos se ve amenazada por los daños causados por la deformación de la pendiente. El desarrollo tectónico y las actividades mineras tienen efectos muy profundos en la estabilidad de la pendiente. Teniendo en cuenta lo anterior, este artículo analizó los efectos de la falla en el control de las características de deformación de la pendiente desestabilizada durante la minería subterránea mediante la adopción del método de simulación numérica desde estas perspectivas, incluido el desplazamiento, el esfuerzo, la tensión, etc., en diferentes circunstancias (con fallas y sin fallas) para proporcionar orientación para los futuros estudios sobre deslizamientos de tierra del mismo tipo y dar propuestas preventivas de referencia.
