摘　　要：采用经验公式计算和数值模拟试验两种方法对榆神矿区小壕兔二号井田2#煤层导水裂隙带发育规律及最大高度进行研究。结果表明经验公式计算值和数值模拟试验结果都显示2#煤层开采产生的导水裂隙带不会对矿区萨拉乌苏组含水层产生影响,都与现场实测值具有良好的一致性;数值模拟试验预测结果与现场实测结果更为接近,说明数值模拟试验相较于经验公式在导水裂隙带最大高度预计方面具有更高的精度和可靠性。The ,development laws and maximum height of water flowing fractured zone in No. 2 coal seam of Xiaohaotu No. 2 Mine field was studied with two kinds of methods, empirical formula calculation and numerical simulation. According to the results, the empirical calculation value and the result of numerical simulation both showed that the water flowing fractured zone caused by mining the No. 2 coal seam had no effect on the aquifer of Salawusu formation, and they were both consistent with field measured value; while the result of numerical simulation was closer to the measured value, which showed that comparing with the empirical formula, numerical simulation had higher accuracy and reliability in the prediction of the maximum height of the water flowing fractured zone.
