AbstractHongxing Mine located in the Longmen Mountainous region is 47km apart from the west of Shifang Town. There are six debris flow gullies in all, in which the debris flows in Modaoshi Gully occur frenquently. In each branch gully, the heavy-rainfall-induced debris flows were caused and in main river (Xiamakou River), collapse-induced debris flow flowed through. Between 1934-1981. The debris flows occurred in 1934, 1976, 1978 respectively. That debris flow of 1934 occurred in most of gullies all at once. Its scale the losses were less because the mine was not built yet. In 1976, the debris flow occurred in an only gully. Its scale was one fourth as small as lost one. but was the largest one in thirty years. Its repetition is above twenty years. At that time, the mine was built about eighteen years, so the losses were heavy. The debris flow of 1978 also occurred in an only gully. The scale was small and the losses were light. These are the basis for considering the developing tendency of debris flows. It is estimaled that the middle scale or small-scale debris flows in Modaoshi Gully will be occur in next 30-50 years. The debris flows may flow through the main river, therefore, it is necessary to take precaution against them. When serious, the debris flow may be caused in many gullies all at once and in main river the largest collapse-induced debris flow will pass through. In case, we should adopt the emergencty measutes, immediately.
