摘要
Huating County is one of 13 major counties which produce coal in China. It is at the beginning of 2005 when massif rift and landslide happened in Cuifengshan neighboring to mining area of Yanbei coal mine in Yanyia town. From the result of investigation, it should be made a conclusion that large-scale mining is main inducing factor causing Yanxia landslide, because mining and engineering activities in the mine field will produce the progressive destruction to geological structure, and this destruction will lead the slope slip.
