| 摘 要： | 山西霍州矿区李雅庄煤矿石炭系太原组K2灰岩岩溶发育,加之区内断裂构造发育,水文地质条件较为复杂。为解决上组2号煤底板太灰突水评价难题,采用GIS的AHP型脆弱性指数法,首先建立煤层底板突水主控因素体系,并通过GIS对主控因素数据进行采集及归一化处理,建立子专题图层,然后运用AHP法确定各主控因素的权重比例,提出煤层底板突水脆弱性的分区方案。与传统突水系数法相比,脆弱性指数法能较为全面地反映不同区域的相对脆弱关系,其评价结果更实际、可靠。

| Abstract: | The kast and fault development in limestone K2 of Carboniferous Taiyuan formation has induced complex hydrogeological conditions in Liyazhuang mining area.. 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 comprehensive relative fragile relationship of different areas and the result is more practical and reliable. |
