ABSTRACT: Generally, the Mos hardness of bauxite is 2.5 to
3.5. According to the specific conditions of the Sangaredi bauxite deposit,
that is, the rock hardness coefficient is between 3 and 6, and there is a
clayey zone in the bauxite mining area, it is necessary to carry out blasting
work before mining. This article mainly analyzes and optimizes the blasting
practice of the Sangaredi open pit bauxite mine. The subject was finally
extended to the reduction of nuisances due to blasting, that is to say
essentially due to vibrations: this presupposed a study around the vibration data available, and the proposal of methods to limit these vibrations. The bottom conditions of the Sangaredi bauxite ore zone are
studied. Bauxite reserves are very rich and the market is huge. The analysis of mine blasting practices, mainly the types of
explosives, the selection and analysis of explosives and blasting
equipment and choosing the mode of longitudinal blasting, the link of the
blasting site of the mining area, further study the optimization of mining blasting practice, the choice of drilling and process to determine reasonable blasting parameters, which improving the
drilling method. The experimental results show that this optimization scheme
improves efficiency blasting of the bauxite mine but also promotes an increase in production.
