At the Mikhailovsky mining and processing plant named after A.V. Varichev (part of the Metalloinvest company) received a new transport and mixing charging machine. It allows the components of water-emulsion explosives (granitemite) to be delivered to the quarry and mixed during the charging process. Granemite is characterized by high safety during work. Water, which is present in its composition, turns into steam during explosion, which also helps to reduce dust formation. According to experts, the amount of dust and gas emissions into the atmosphere, compared with the use of TNT-containing explosives, is reduced by up to 6 times.
Equipment worth about 26 million rubles was purchased as part of Metalloinvest's program to modernize the mining transport complex and improve environmental friendliness blasting operations in the quarry of the plant. In total, 6 transport-mixing charging machines are used at Mikhailovsky GOK.
The new vehicle is based on the KAMAZ chassis and is compact, maneuverable and maneuverable. It is equipped with an automated control system that allows you to control the parameters of the technological process of preparing explosives, carry out diagnostics, and warn of emergencies. In addition, the equipment has a new generation fire extinguishing system and has high transport safety.
"Such special equipment has been used at the plant since 2001 - with the commissioning of its own complex for the preparation of components of water-emulsion explosives," explained the head of the blasting section of the BVU Mikhailovsky GOK named after A.V. Varicheva Ivan Petkov. - Currently, the transport and mixing charging machine is undergoing the stage of commissioning, but already now we see that it is much more convenient than its predecessors. For example, the control monitor is located in the immediate vicinity of the charging arm, which improves the quality of control over both well charging and equipment operation. "
