摘要
以潘谢矿区某综采面为例，分别采用经验公式预测、数值模拟演算、现场试验等三种方法，初步探究了综采工作面覆岩运动导水裂隙带高度的发育特征，用三种方法得到结果分别为34．03～49．50，47．92—58．71，50m，通过对比分析发现，经验公式预测结果偏小，数值模拟的结果和现场试验结果较吻合，最终确定导水裂隙带高度为50m。
In order to explore the characteristics of the growth height of water- fractured zone of fully mecha- nized working face, a fully mechanized coal face in Panxie Mining Area was used as an example. Actually , I study on the issue in three ways： the empirical equation, numerical simulation calculation and field test , though which the results were 34. 03 - 49. 50, 47. 92 - 58.71,50 meters respectively. Through the compar- ative analysis, we can find that the result was obviously smaller by using empirical formula to calculate ,while the results of numerical simulation were fit well with the field test results, as a result, it＇ s concluded that the height of water- flowing fractured zone is of 50 meters high.
