| 摘 要： | 目前，径向射流孔的长度可达百米，使该技术在矿井防治水方面具有了一定的实际应用价值。2015年在邢台矿采用该技术对断层的产状进行了探测，对其在断层产状探测、定位方面的应用进行了研究。通过对在砂质泥岩、铝土岩、本溪组灰岩、奥陶系灰岩中的射流压力、遇阻过程及其他异常状况的综合分析，得出了径向射流技术在断层产状探测时，适用地层岩性主要为灰岩，断层两盘岩性不同时径向射流探测结果准确的结论。

Application of radial jet technology in detection of fault occurrence and location |
| |
| Abstract: | At present, the length of the radial jet hole is up to 100 m. Thus the technology has practical application value in the field of water prevention in mines. In 2015, the technology was used to detect the fault in Xingtai mine. The application of this technology in fault detection and location was studied. Based on the comprehensive analysis of jet pressure and resistance process in sandy mudstone, bauxite, limestone, it is concluded that when the radial jet technology was applied to detect the fault occurrence, the detection results of radical jet were accurate when the strata were mainly limestone and the two walls of fault were different lithologically. |
