"ҚАЗАҚАЛТЫН ТМК" АҚ ЖОЛЫМБЕТ КЕН ОРНЫНДА БҰРҒЫЛАУ-ЖАРУ ЖҰМЫСТАРЫНЫҢ ТИІМДІЛІГІН ЖЕТІЛДІРУ

The experience of using the technology of production of drilling blasting operations in deep quarries when leaving Kemer behind by the method of pre-drilling with the use of a special contour charge zkv-B, as well as the experience of improving the technology of drilling blasting operations and the design of explosive charges in the industrial conditions of Quarry No. 6 at the Zholymbet Fields was considered. The method of creating preliminary slots using the special contour charge ZKV-B plays an important role in improving the efficiency of drilling and blasting operations in deep quarries. This method ensures stability when leaving behind the benches, preventing excessive destruction of rock masses. The pre-created slots protect the rocks on the edges of the quarry, enhance production safety, and improve the quality of blasting operations. Additionally, ZKV-B charges precisely define the quarry contour, efficiently direct the blast wave, and reduce harmful impacts. The experience of improving the drilling and blasting technology in the specific industrial conditions of the No. 6 quarry at the Zholymbet deposit was aimed at further enhancing the efficiency of this process. In particular, the improvement of explosive charge designs contributes to the optimal use of blast energy, reducing energy loss in rock fragmentation and increasing safety levels. The improvement of drilling and blasting technology results in better quality mineral extraction without damaging the quarry walls. The application of these methods in practice contributes to increasing the economic efficiency of production and meeting environmental requirements. Continuous improvement of explosives and drilling and blasting technologies ensures safe and efficient operations in deep quarries while also reducing risks associated with deposit development.
