ANALYSIS OF RESEARCH ON BLASTING OPERATIONS IN THE PREPARATION OF WATER-FILLED OVERBURDEN BLOCKS IN OPEN-CUT MINES

https://doi.org/10.48498/minmag.2025.247.11.001

The article examines the problems of rock mass preparation during stripping operations in open-pit mines in conditions of waterlogging. It provides an overview of the basin’s geological characteristics, regulatory and methodological documents for drilling and blasting operations, and actual consumption rates of explosives. The impact of waterlogging on slope stability, equipment productivity, and the economics of stripping operations is analyzed. Three groups of measures to reduce waterlogging are described : general quarry, local, and process; surface, underground, and combined drainage methods are considered. Particular attention is paid to preliminary contour blasting as a local method for creating drainage zones. A conclusion is drawn regarding the need for systematic research into the conditions for applying local and quarry measures to improve the efficiency and safety of blasting operations in waterlogged massifs.
