Geological hazards often occurred in Jiaozuo City because of large-scaled exploration of minerals, which caused enormous economic loss and big casualties. Geological hazard assessment of reconstruction project in a village in Jiaozuo City was conducted as an example. The ratio of mining depth to mining thickness and the ground surface displacement were estimated by statistics method. The risk of occurring land collapse and ground fissure in the typical area in Jiaozuo City was discussed. Finally, the countermeasures were put forward.
