Abstract

The invention discloses an advanced detection method and an advanced detection system for a roadway. According to the advanced detection method for the roadway, apparent resistivity data is obtained;theoretical background apparent resistivity data are also acquired; the theoretical background apparent resistivity data and the correction coefficient corresponding to each measuring electrode are utilized to correct the apparent resistivity data detected by each measuring electrode; so as to eliminate the adverse influence of the tunnel cavity on the signal-to-noise ratio of the data, a problemof low signal-to-noise ratio of the data caused by influence of the tunnel cavity can be excellently solved, detection resolution and accuracy are improved, and quantitative data processing and explanation basis is provided for geophysical exploration personnel.

Description

technical field [0001] The present application relates to the technical field of roadway detection, and more specifically, relates to a roadway advanced detection method and an advanced detection system. Background technique [0002] The roadway is a variety of passages drilled between the surface and the ore body, which are used for ore transportation, ventilation, drainage, pedestrians, and various necessary preparations for new excavation of ore for metallurgical equipment. These passages are collectively referred to as roadways. . [0003] Roadway advanced detection refers to the technology of detecting the situation in front of the face of the roadway (that is, the unexcavated direction). At present, a variety of geophysical methods have been developed, such as seismic reflection method, transient electromagnetic method and direct current method. The seismic reflection method has a good response effect on the structural interface, but has a poor response effect on the ...
