Ground three-component magnetic orientation method and ground three-component magnetic orientation exploration device

Abstract

The invention provides a ground three-component magnetic orientation method which can finish sensor three-axis self orthogonal correction and sensor three-axis coordinate and geographical coordinate conversion. The invention furthermore provides an oriented exploration device based on the ground three-component magnetic orientation method. The oriented exploration device comprises a probe, a controller module, a clock control module and a power module. The probe comprises a sleeve which is internally provided with a non-magnetic titanium alloy trough in which a sensor module is mounted. The sensor module comprises a positioning module, a flux gate sensor and an inertia measurement module. The positioning module, the flux gate sensor, a matrix keyboard and a liquid crystal display module are connected with the controller module. The ground three-component magnetic orientation method and the ground three-component magnetic orientation exploration device can perform quick measurement and furthermore can acquire spatial geomagnetic field parameters which are more abundant than that of a traditional proton magnetometer, thereby providing omnibearing geophysical data for geological prospecting. Furthermore the ground three-component magnetic orientation method and the ground three-component magnetic orientation exploration device can settle a point fixing problem in field survey grid and realize one-step completion in field three-component magnetic survey.

Description

technical field [0001] The invention relates to a ground three-component magnetic force orientation method and a ground three-component magnetic force orientation exploration device, belonging to the field of geophysical exploration. Background technique [0002] Magnetic prospecting is based on the magnetic difference between rocks, ores (strata) and their surrounding rocks. Special magnetic instruments and equipment are used to observe and study the changing laws of the physical field, so as to find out the geological structure, find mineral resources and solve hydrological problems. , engineering geological problems and environmental monitoring and other issues. Looking at the trend of magnetic prospecting, the first stage is scalar measurement, the second stage is gradient tensor measurement, and the third stage is vector measurement. At present, my country's field mobile magnetic survey is mainly based on the single parameter measurement of the total magnetic field, wh...

Problems solved by technology

This kind of three-component magnetic measurement is not as mature as those of the previous instruments in terms of measurement technology, data processing, graphic display and interpretation, especially the calibration of the three-axis coordinates. It takes a lot of time for three-axis orientation, so the work efficiency is low. This is one of the main reasons why the three-component magnetometer is not popularized and promoted in our country at present.

Therefore, currently, there are few users who use the three-component magnetometer. In order to overcome the disadvantages of the above-mentioned three-component ore prospecting on the ground, the research and development of this instrument has been specially carried out.
