| 摘 要： | 双频激电法煤矿巷道实时超前探测技术是基于岩(矿)石的激发极化效应,发射极和屏蔽极同时发射高、低频交流电,使掘进面前方的岩石得以充分极化。测出高低频电位差特性,通过分析和计算得出视电阻率值和视幅频率,间接推断工作面前方隐伏地质构造,为掘进工作提供可靠的理论数据依据。 |
| 关 键 词： | 激发极化 极化效应 双频交流电 超前实时探测 视电阻率 |

| Abstract: | The real-time pilot detection technology based on the double frequency induced method of the mine roadway is to fully polarize the rock in front of the roadway heading face with the rock(mineral) induced polarization effect,and the high and low frequency AC emitted from the emitted pole and shield pole.The high and low frequency potential difference features were measured.With the analysis and calculation on the apparent resistance value and apparent width frequency rate,the hidden geological tectonics in f... |
| Keywords: | induced polarization polarization effect double frequency AC pilot real-time detection apparent resistivity |
