摘　　要：为对准格尔煤田中部黄玉川煤矿4号和6上煤层底板奥灰含水层突水危险性进行分区,通过分析研究区范围内奥灰含水层水位和目标煤层底板标高,得到了各煤层底板带压分区,构建了研究区突水危险性评价指标体系。在此基础上,利用基于AHP的脆弱性指数法对研究区范围内煤层底板奥灰突水危险性进行评价与分区。评价结果表明,研究区范围内4号煤层大部分为安全区和较安全区,6上号煤层危险区和较危险区显著增加,主要集中在研究区西部及东部的构造发育区。研究结果对黄玉川煤矿的安全开采具有指导意义。In order to make a zoning of water outburst risk of Ordovician limestone aquifer in the floor of No.4 and No.6 upper coal seam in Huangyuchuan Mine in the central part of Zhungeer coalfield,the water level of Ordovician limestone aquifer and the elevation of target coal seam floor in the study area were analyzed,and the pressure zoning of each coal seam floor was obtained.The evaluation index system of water outburst risk in the study area was constructed.On this basis,the vulnerability index method based on AHP was used to evaluate and zone the risk of Ordovician limestone water outburst from coal seam floor in the study area.The evaluation results showed that most of No.4 coal seam in the study area was safe area and relatively safe area,and the dangerous area and relatively dangerous area of No.6 upper coal seam increased significantly,which mainly concentrated in the western and eastern structural development areas of the study area.The research results had guiding significance for the safe mining of Huangyuchuan Mine.
