Abstract

The invention discloses an open pit mine main access segment blasting hole net parameter determination method and belongs to the technical field of blasting engineering. The open pit mine main access segment blasting hole net parameter determination method comprises of dividing an open pit mine main access into t (t is greater than or equal to 2) blasting segments including the first segment, the second segment, ...... and the tth segment; determining the total step height of the open pit mine main access and conducting calculation in sequence to obtain blasting hole net parameters; and implementing segment blasting hole by hole according to the calculated blasting hole net parameters. By acquiring the known easily obtained parameters and through the formula and principle, other hole net parameters of segment blasting are obtained scientifically and accurately; and the construction time and cost can be saved. Moreover, through the hole-by-hole blasting technology, the single-segment blasting explosive quantity can be reduced, the influence of the blasting vibration strength on the slope stability is reduced, the road surface quality of the main access is improved, and the running efficiency of an automobile is improved.

Description

technical field [0001] The invention relates to the technical field of blasting engineering, in particular to a method for determining hole network parameters of sectioned blasting in an access ditch of an open-pit mine. Background technique [0002] Trenching in open-pit mines is an important part of open-pit mines, and its excavation efficiency and quality directly affect the progress of new bench mining and the stability of the slope. Trench blasting in open-pit mines can be divided into full trench blasting with equal deep holes and blasting with unequal deep holes along the slope. Full trench and other deep hole blasting is based on the high penetration blasting of the entire section of the step. The entry and exit trench is formed by excavating shovels according to the slope and length of the entry and exit trench. Half of the blasting volume is left at the bottom of the trench. This method is mostly used for temporary or short-term slope cuttings. The advantage of tr...
