In order to solve the problem of water inrush evaluation in the floor of the second seam in the limestone of upper Taiyuan formation, we used the AHP vulnerability index method of GIS. Compared with the traditional water inrush coefficient method, the vulnerability index method reflects more com- prehensive relative fragile relationship of different areas and the result is more practical and reliable.
