摘要
以矿压理论、"上三带"理论为基础,从岩层碎胀特性及岩层组合运动出发分析,分别推导出了垮落带高度为(2.17~1.67)倍的采高、裂隙带高度为(6.67~10)倍的采高,从而推导出了导水裂隙带的初步预计高度为(8.34~12.17)倍的采高,依据煤矿地质条件和开采条件进行具体分析,得到导水裂隙带最终预计高度,并得到了现场实测验证。
On the basis of ground pressure theory, and upper 3 zones theory,by analyzing the expansion property of rock and strata combination movement,deduced the height of the caving zone and fractured zone are（2.17-1.67） and （6.67-10）minable coal thickness respectively,thus determining the water flowing fractured zone preliminary estimate height is （8.34 - 12.17） times the mining height,carrying out specific analysis on coal geological conditions and mining conditions,obtained final estimate height of water fracture zones,And verified by the field measured result.
