Abstract：In order to make full use of the existing data and improve the accuracy of evaluation, GIS technology was applied in the evaluation of coal floor water inrush, in the evaluation of No. 8 coal seam floor Cambrian limestone water in Sitai mine. First, the two thematic maps of aquifuge thickness and water pressure affecting coal floor water inrush were established based on GIS. Secondly, the value of water-inrush coefficient was obtained in overlay analysis, and the result was divided into two types. Then, the evaluation information system of floor water inrush based on GIS is developed. Further, the results of GIS-based evaluation was compared with that based on the traditional drilling point, which showed the water inrush coefficient method based on GIS was more consistent with reality. The successful application of GIS technology in coal floor water inrush provides technical support for effective control of coal seam floor water inrush.
