Abstract: A large number of spatial and attribute data are involved in coal resources evaluation.For the deficiency of traditional evaluation methods the corresponding software is developed based on MapX,and the spatial and attribute data are managed integrally.The complexity of Fault Network is evaluated quantitatively in Liuqiao No.2 coal mine.The results indicate that parameters of models can be obtained effectively in the evaluation using GIS,making the data and evaluation result more intuitionally,and a kind of effective way for the coal resources evaluated is offered.
