摘　　要：为提高煤层底板水害评价精度,以四台沟矿区开采煤层底板水害评价为例,在基于GIS技术的基础上将脆弱性指数法和突水系数法进行比较分析,选择较优的评价方法。通过GIS技术,利用脆弱性指数法在承压含水层、地质构造、底板隔水层三个层次下建立了主控因素专题图,运用层次分析法确定各项权重,并进行专题图叠加生成评价分区图,利用突水系数法得出评价分区,经过对比两者的精确度,基于GIS的脆弱性指数法更接近实际情况,对煤炭的安全开采更具有指导性。In order to improve the evaluation accuracy of coal floor water damage, taking the evaluation of coal floor water hazard in the Sitaigou Mining Area as an example, the vulnerability index method and water inrush coefficient method based on GIS technology are comparatively analyzed, and the better evaluation method is selected. Through the use of GIS technology, using the vulnerability index method, thematic map of main control factors was established under the three levels： confined aquifer, geological structure and floor aquiclude. The analytic hierarchy process was used to determine the weights and thematic maps were superimposed to generate the zoning map. When using water inrush coefficient method we got the result of evaluation partition. We can conclude that the GIS-based AHP analytic vulnerability index method is closer to the actual situation and more instructive for safe coal mining, according to accuracy comparison of the two methods.
