摘要
分析了矿井顶板水害及防治现状 ,以兴隆庄煤矿 4 31 8工作面为例 ,用信息拟合方法对顶板富水性进行分区 ,应用模糊评判预测方法进行了顶板水量预测计算 :涌水量等级为 3级 ,正常涌水量为 0 .5～ 1 .5m3/ min,最大涌水量为 2 .2 5m3/ min,与实际涌水量一致。
In this paper,the actuality of water disaster and its control are analyzed.It is introduced that the dim judgement method of forecasting water yield,which is finished on the basis of water content division of roof aquifer by using the method of drawing up with the information.To take 4318 working face in Xinlongzhang coal mine as a example,the water yield from top water bearing body is forecasted;the water yield is divided 3 grages.Normal water yield is 0.5～1.5 m 3/min,maximum water yield is 2.25 m 3/min,that coincides with measured water yield.
