Geohazard Forecasting in Mining Area Based on Grey Model

This paper studied a forecasting method of geological hazard in loess plateau mining area, by making use of a grey system theory and building grey model, it is expected that in 2018, the loss statistics of mining geology hazard in the area will increase steadily, the loss of water-inrush, slag, ground subsidence, landslide collapse and ground crack will reach relatively 623,480 dollars, 879,346 dollars, 75.833 km2/103km2, 811.295*104m3, 597,761 dollars in 2018. The prediction results provided geological bases for the economic and social sustainable development, ecological environment construction and protection.
