摘　　要：为准确评价赵家寨矿12采区东翼二_(1)煤层顶板突水问题,选取导水裂隙带高度、导水裂隙带高度范围内的含水层厚度、新近系含水层的富水性、剩余黏土层厚度、断层分维值5个因素作为煤层顶板突水的主控因素,运用层次分析法确定各主控因素对总目标的影响权重,并通过自然分级法确定研究区的分区阈值,最终获得了研究区二_(1)煤层顶板突水危险性评价模型。评价结果与后期工作面开采的疏水结果相一致,实际疏放水量与预测静水储量吻合度达96.7%,实现了二_(1)煤层的安全回采。In order to accurately evaluate the water inrush problem of theⅡ_(1) coal seam roof in the east wing of the 12th mining area of Zhaojiazhai Coal Mine,five factors were selected as the main controlling factors for water inrush of the coal seam roof,including the height of the water conducted zone,the thickness of the aquifer within the height range of the water conducted zone,the water richness of the Neogene aquifer,the thickness of the remaining clay layer,and the fractal dimension value of the fault.The influence weight of each main controlling factor on the overall target was determined by the analytic hierarchy process,and the partition threshold of the study area was determined by the natural classification method,and finally obtained the risk assessment model for water inrush of theⅡ_(1) coal seam roof in the study area,the evaluation results were consistent with the drainage results of the later working face mining,and the actual water drainage and the predicted static water reserves matched up to 96.7%,realizing the safe recovery of theⅡ_(1) coal seam.
