Abstract

The invention relates to a transient electromagnetic coil leveling device for field detection and a method of using the same. The device mainly comprises automatic leveling mechanisms, a transmittingcoil fixation mechanism, a receiving probe fixation mechanism, a console mechanism, and a roller traveling mechanism. The automatic leveling mechanisms are arranged at four corners of the device; thereceiving probe fixation mechanism and the console mechanism are connected to the transmitting coil fixation mechanism. The transmitting coil fixation mechanism is in contact with the ground surface through four rollers, so that the device is convenient to move and data are collected conveniently. The transmitting coil fixation mechanism can be lifted by reeling or unreeling of the rollers; and the receiving probe and the transmitting coil are lifted simultaneously to ensure effectiveness of a transmitting pulse magnetic field and the receiving signal. The device is operated simply with high practicability, the influence by the terrain can be eliminated; the collection quality efficiency is improved; the labor intensity of the personnel is reduced; and the credibility of the data is enhanced.

Description

technical field [0001] The invention relates to the field of geophysical detection, in particular to a transient electromagnetic coil leveling device suitable for field detection and a method for using the same. Background technique [0002] Transient electromagnetic method is a method with great development prospects, which can find out water-bearing geology such as karst caves and passages, coal mine goafs, deep irregular water bodies, etc. The transient electromagnetic method is the most sensitive method in increasing the detection depth and finding low-resistance geological bodies in high-resistivity areas. It can automatically eliminate the main noise source, and has no terrain influence. Combining observations at the same point has the best coupling with the detection target and abnormal response Strong, simple shape, strong resolution and other advantages. [0003] However, the work on the ground is relatively complicated and boring. At present, the transient electro...
