| 摘 要： | 导水裂隙带高度的确定为矿井安全开采提供设计依据,通过对钻孔测导高简易水文曲线特征及巷探资料的研究,突变型、渐变型、波变型3种类型的导水裂隙带顶界面,都应以完全中断循环的深度确定导高临界面位置.淮南矿井实例研究结果表明按突变型、渐变型、波变型来确定临界导高位置方法可行实用.

| Abstract: | Determining the height of a permeable fracture belt provides the design basis for the coal safety mining,through the research of drilling＇s characteristics of simple hydrographic curve and tunneling prospecting data,mutant-type,gradually-varied and wave-varied＇s top interface of permeable fracture belt should be determined the critical surface of the height of a permeable fracture belt with the depth of interrupt cycle.Cases studies in Huainan Mines show that methods of determing the height of a permeable fracture belt by means of the mutant-type,gradually-varied and wave-varied＇s top interface of permeable fracture belt are feasible and practical. |
