摘要
为充分了解81201工作面覆岩导水裂隙带的发育规律及高度,采用钻孔取芯的方式对钻孔的冲洗漏失量和岩芯特征进行综合分析,得出导水裂隙带的发育高度。结果表明:81201工作面导水裂隙带的高度为137.3m。
In order to fully understand the development law and height of water flowing fracture zone of overburden strata at 81201 working face, the paper comprehensively analyzes the flushing leakage and core characteristic of the drilling hole by means of core drilling and obtains the development height of water flowing fractured zone. Results show that the height of water flowing fracture zone at 81201 working face is 137.3 m.
