Abstract:

The radius of the danger zone with loose rock lands when blasting in open mines ỈS calculated according to national technical regulation QCVN 02: 2018 / BCT throuA various blasting methods. In addition to tiMj conventional geometrical parameters, the radius of the danger zone caused by the fragments scattered by rocks and blasting also depends on the type of explosives, the powder factor and the total amount of explosives used.. The paper introduces the basis of the method of calculating the kinetic energy formation conditions of rock fragments when blasting on open mines with different blasting methods. Here, the authors forecast the impact radius of rock splashing due to blasting on open-pỉt mines, or ỉn mountainous terrain in Vietnam.
