钻探法研判断层走向在煤巷掘进中的应用

Application of drilling method to judge stratum strike in coal roadway excavation

煤巷掘进过程中经常遇到较大的断层,不但降低了煤巷掘进速度,使接替变得紧张,给工作面的回采工作带来较大的影响,遇到较大断层时,如何通过钻探法快速、准确的确定断层走向,怎样根据断层走向避开断层合理的布置巷道,都关乎着煤矿的安全高效生产。通过钻探法对三河尖煤矿73103工作面断层发育规律及断层走向进行了详细的研判及论述,有效地保障了煤巷正常掘进、保障了矿井安全高效生产。

Large faults are often encountered in coal roadway excavation,which not only reduces excavation speed of coal roadway,makes connection tense,and has a great impact on mining work of working face.When encountering large faults,how to quickly and accurately determine fault direction through drilling method,and how to avoid fault and reasonably arrange roadway according to fault direction are related to the safe and efficient production of coal mine.Through drilling method,the fault development law and fault strike of 73103 working face in Sanhejian Coal Mine are studied and discussed in detail,which effectively ensures the normal excavation of coal roadway and safe and efficient production of mine.
