Abstract Now, Qing-Zang railway is being built, much frozen soil is needed to be blasted, but the literatures about frozen soil blasting in home and abroad is few. The paper describes a few explosion craters carried out in certain place of Qing-Zang railway, the optimum depth and maximum volume are obtained, and the optimum blasting parameters are also found out.
