Abstract: It pointed out the importance of setting up regional geologic database and on-site survey analysis by using the example of safety pre-evaluation of Wangjialing Coal Mine. It also proposed problems needing attention for safety pre-evaluation, such as the specialized structures of evaluators, the reference of geologic data and the pertinence of safety countermeasures suggestions. It indicated the dangerous and hazardous factors of construction projects. Only based on completely understanding of actual data, it carried out accurate recognition analysis and put forward to scientific, reasonable, feasible safety countermeasures, the due role of safety pre-evaluation for coal construction projects would be played.
