The Congolese State provides 435 million dollars for the effective relaunch of mining activities at MIBA. The investment of these millions of dollars is spread over 5 years, including 161 million for the first two years of the five-year term and the difference in the next three years.
While waiting for the first installment of the investment budget, MIBA intends to timidly start mining the kimberlite from the Massif 1 site in the first two years of the five-year term. This kimberlite will be fed to the three processing plants to be operationalized sequentially, and having a CUP of 0.49. Based on the CUP of the factories and the fleet of available machines, we have sized the machine park for the partial relaunch of mining activities. This machine park will consist of 2 probes, 3 excavators, 2 loaders, 6 trucks, 1 dozer, 1 grader, 1 compactor, 200-meter-long piping in place of a tanker truck, a machine refueling pump on site, movable on board a vehicle and safety equipment.
The objective of this work was to valorize the waste rock from the Bakwanga Colline Zone 4 mining site of the MIBA with pockets and layers of gravel containing more than 10 carats of diamonds per cubic meter, but abandoned because of the large volume of waste rock to excavate and move. To recover this waste rock, it is important to identify them and classify them in a category of construction materials. Soil identification and classification work based on the USCS, AASHTO, LCPC systems and many other classification standards (XPP 94-011) incates that these are SP sands or poorly graded sands or still group A-3 sands, non-plastic, non-organic, non-marly and compact. These soil classification systems indicate that the soils studied are among the soil classes with the best behavior as road infrastructure materials. They are also used in civil engineering works such as compacted earth dams in the shoulders and in the foundations. Studies made on the same types of soils in certain corners of the city of Mbuji-Mayi indicate that these soils can also be used for the manufacture of baked bricks or stabilized bricks.
