AUTOMATED GRAVIMETRIC SYSTEM WITH ELEMENTS OF ARTIFICIAL INTELLIGENCE TO SEARCH FOR MINERALS

Abstract

The article is devoted to a topical problem – gravimetric study of the Earth for the presence of mineral deposits. To solve the problem, a system of automated gravimetric surveying with elements of artificial intelligence for the search for minerals has been developed. The proposed system of intelligent determination of minerals in gravitational exploration works uses a two-channel capacitive gravimeter as a sensitive element. The advantages of this system include: the speed of determining the key points where there is a deviation of free fall acceleration, the ability to work in hard-to-reach regions of the globe with unmanned aerial vehicles, high accuracy through the use of the last two-channel capacitive MEMS gravimeter. The advantages of MEMS (Micro Electro-Mechanical System) include high accuracy compared to analog devices, low cost of production in mass production. The small size of MEMS-gravimeters allows to expand the scope and increase the functionality of use in miniature research systems. The high accuracy of the gravimeter used in the system is achieved by reducing the main measurement errors by using two channels. The advantages also include efficiency, as it does not require the use of a large number of expensive devices and systems. The dependences of mineral on the magnitude of free fall acceleration are determined in the work and fuzzy rules of their determination are developed. According to engraving, conducted using the proposed automated gravimetric system with elements of artificial intelligence, we can with some probability talk about the presence of minerals such as copper, magnetite, coal and others. At the same time information processing time is reduced. Further clarification of the depth and size of the mineral deposit requires additional geological and geophysical research, such as the use of remote spectral and structural analysis of minerals with the involvement of satellite exploration.
