Abstract: In view of the rock mass dynamics characteristics and drilling-blasting construction challenges in plateau alpine freeze-thaw environments, the influence mechanism of freeze-thaw cycles on rock mass strength degradation was systematically analyzed, as well as the constraints of uneven frozen soil layers, blast hole water gushing and freezing, and borehole deviations on blasting efficiency. Three practical solutions were proposed based on engineering practices, including borehole attitude parameter measurement technology, blast hole deicing （thawing） technology, and combined deep-shallow blasting technology. The attitude parameters for straight-arc boreholes can be measured, and the high-pressure gas deicing method was adopted to address blast hole water gushing and freezing. Meanwhile, the influence of uneven frozen soil layers on blasting parameters was mitigated, thereby improving blasting quality. These technologies successfully tackle the complex conditions in plateau alpine regions, overcoming the challenges posed by freeze-thaw rock. Additionally, they not only improve the safety and economy of blasting operations in plateau mines, but also provide critical technological support for the infrastructure construction of alpine regions, demonstrating notable engineering application significance and social benefits.
