Abstract

Fracture caused by mining in mountain is the major influencing factor of inducing slope landslides.The paper studied the difference of fracture during upslope mining and downslope mining at working face with the UDEC numerical simulation.The research shows that the fractures under additional stress action are difficult to formed on lower parts and toe of slope during upslope mining,and they are easy to formed on the top and central of slope during downslope mining;the tractional normal fractures are formed during upslope mining,and promoted reverse fractures are formed during downslope mining;the distance of the advance fracture during upslope mining is greater than that during downslope mining.
