Abstract
The purpose of this study is to develop an effective drilling and blasting technology that will improve the productivity and safety of blasting operations during the construction or development of rocks. The study describes the examination of the Kariernoie gold deposit in Kazakhstan using geological and mining methods and materials, including analysis of the gold content in ores, assessment of the capacities of ore bodies, determination of the chemical composition of the ore, and conducting studies to optimise the extraction process. The productivity of the equipment and personnel involved is substantially reduced, and the cost of rock excavation and preparation for explosion increases. Hydrogeology manifests itself in the selection of various explosive materials, the justification of charging methods and methods of forming charges in boreholes, and the choice of technical means and technical measures to reduce the negative consequences of waterlogging. In some cases, the removal of water from the well can reduce the water level in a relatively short time. Therewith, there are explosive blocks where the flow of water into the well is comparable to the performance of a pump of special equipment for pumping water, and the decision to use special equipment for pumping water is clearly impractical. The development of an effective drilling and blasting technology is of high practical importance for the oil and gas industry, as it can increase the productivity and safety of workers and reduce the cost of good operation, which is an urgent problem in this industry.
