摘　　要：以宁夏宁东矿区为研究区,将层次分析法与GIS相接合,首先利用层次分析法建立层次结构模型,确定影响煤层可采性各指标的权重,然后利用GIS建立各影响指标空间结构模型,提取各影响指标并进行权重赋值,确定各影响指标的空间拓扑关系,然后根据各影响指标的空间拓扑关系对权重值进行组合分析,最后得到研究区煤层可采性安全评价综合分区图,以满足宁夏规划的火电基地和煤化工项目对优质环保型煤炭资源的需求,做好煤炭开发过程中灾害预测和防治工作,为资源开发和环境保护提供依据。Taking East Ningxia Mine for example, AHP was used to establish the hierarchical structural model and define weights of indexes that influencing workability of coal bed ; then GIS was used to build the spatial structural model of all influence indexes, extract and weight the indexes, define the spatial topological relationship of all influence indexes, combine and analyze the weighted value according to the spatial to- pological relationship, and finally get the security evaluation comprehensive zoning of the coal bed workability in the study area. This study provided the basis for meeting the need of thermal power base and coal-to-chemicals projects projected in Ningxia for high-quality and environ- ment-friendly coal, and for the disaster forecast and prevention during coal exploitation, and for the resource exploitation and environment pro- tection.
