Abstract
In terms of Kangalassky Open Pit Mine, the authors discuss in situ monitoring of temperature on the surface of blasted overburden rock mass in the course of gradual dragline operation. It is shown that dragline capacity can be related with the surface layer temperature and average size of the blasted overburden fragment.
