摘 要:针对掌石沟煤矿在采用传统地面打钻法确定煤层导水裂隙高度时,存在钻孔施工工程量大、测量精度低以及工程费用高等技术难题,通过技术研究,对传统导水裂隙高度测量方法进行优化,提出了观测仪观测法,并在15102工作面中进行应用。实际应用效果表明:与传统观测法相比,采用观测仪观测法确定煤层导水裂隙带高度时,具有钻孔深度小、精度高、受施工环境影响小等优点;利用该法准确测定了15102工作面上覆岩层导水裂隙带高度为29 m,取得了显著应用成效。In response to the technical difficulties of large drilling construction quantity,low measurement accuracy,and high engineering cost when using traditional ground drilling method to determine the height of coal seam water conducting cracks in Zhangshigou Coal Mine,through technical research,the traditional method for measuring the height of water conducting cracks was optimized,and the observation method was proposed and applied in the 15102 working face.The practical application results show that compared with traditional observation methods,the use of observation instruments to determine the height of coal seam water conducting fracture zones has the advantages of small drilling depth,high accuracy,and little impact from construction environment.The height of the water conducting fracture zone in the overlying strata of the 15102 working face was accurately measured to be 29 meters using this method,and significant application results were achieved.
