This conference invited several excellent geophysical experts from Rio Tinto Group to give lectures and share experience. We have learned some advanced scientific methods used in geological exploration. This will help us become a more professional geological product supply team at home and abroad, and lay a solid foundation for providing customers with better services.
Electrical Resistivity Tomography Survey refers to the DC high density resistivity method, but because of the development of dc excitation polarization method, so referred to as the electrical resistivity tomography method. The resistivity tomography method is actually a method of array exploration.
Electrical Resistivity Tomography (ERT) is an advanced geophysics method used to determine the subsurface’s resistivity distribution by making measurements on the ground surface. ERT data are rapidly collected with an automated multi-electrode resistivity meter. ERT profiles consist of a modeled cro
A geoelectrical survey using the electrical resistivity method was carried out to investigate the sub-surface layering and evaluation of the aquifer characteristics. Applying the Schlumberger array, a total of 596 vertical electrical soundings were conducted along 26 profiles. Quantitative and quali
① To further identify the shape, occurrence and geological conditions of the ore body, including identifying the boundaries around the ore body and putting forward accurate geological maps, so as to determine a reasonable mining plan.② To find out the industrial grade, mineral composition, structura
From accuracy and efficiency, the technology of GPS drone mapping has been mature.One of the most valuable indicators is survey accuracy , the survey accuracy is directly affected by the application. From the traditional GPS positioning to RTK / PPK / PPP, the drone gps mapping survey is one of tech
The rig is a host that completes the drilling construction, it drives drilling tools and drill bits to the depth of the formation drilling, and through the lift on the rig (hoist) to complete the drilling tools and casing, extraction of core, replacement of drill bits and other auxiliary work.The ma

Transient Electromagnetics Method TEM is based on the difference between the electrical conductivity of rock (ore) in the earth's crust and the magnetic conductivity of DAO. According to the principle of electromagnetic induction, a pulse magnetic field is sent underground by using ungrounded loop o
Drone is widely used, with low cost, multitasking, good maneuverability, high efficiency, low radiation, widely used in various aspects of military and civil production. Since GPS has the characteristics of all-weather, high precision and automatic measurement, drones currently used for mapping are basically used to locate and navigate through GPS. The GPS single point positioning accuracy of the drone flight control is too bad. So RTK technology and PPK technologies are apllied on drone mapping, which both can reach cm accuracy.
