Abstract

While large mining companies have financial and human capital to invest in cutting-edge technologies to monitor their production process, small and medium-sized companies, which represent the vast majority of companies in this sector (95% in Brazil) are left destitute. Although these smaller companies have the need to acquire new technologies, they have difficulties in financial and human investment in solutions of this type. This project aims to develop an accessible System for small and medium-sized mines, capable of providing real-time information on mining equipment (trucks, excavators, etc.), plant equipment (crushers, belt conveyors, etc.) and maintenance (consumables per km, etc.). The precision in the location of the sensor of the mining equipment will be compared with a high precision portable equipment of multiple GNSS (GPS, GLONASS and Galileo) and with the real georeferenced position. Three situations will be tested. The first will be fixed in an open area, in good conditions for viewing the satellites. The second will be fixed in the lower part of a pit, where it presents the greatest challenge for collecting accurate information. The third will be on the move. The accuracy of the current sensor of the plant equipment will be compared with a high precision portable equipment and with the equipment current sensor. Ten situations will be tested. The first five will be with the equipment in good condition connected without material, with 25% of capacity, with 50% of capacity, with 75% of capacity and with 100% of capacity. The last five will be with the equipment in poor condition, for example, if it is tested on a belt conveyor, it will be with some locked rolls. The expected results at the end of PIPE Phase 1 are: 1 - That the mining equipment sensors collect their positions, send it to the server, which will identify whether the equipment is loading, unloading, transporting empty and loaded, in line and in maintenance; 2 - That the sensors of the plant equipment collect the current, send it to the server, which will identify the amount of material present in the equipment or the probability of failure. With this system, smaller mines, responsible for most of the construction materials, such as sand and gravel, will be able to make decisions based on information, reducing costs and increasing productivity. The system will improve mining performance, which will consequently provide products at a lower cost to society. In addition, with the lowest consumption of fuel and electricity, less ton of greenhouse gases should be emitted for each ton of ore produced and processed. (AU)
