Modified blast hole blocking material applied to strip mine blasting and preparation method
The invention discloses a modified blast hole blocking material applied to strip mine blasting and a preparation method, and belongs to the technical field of mine blasting. The modified blast hole blocking material comprises the following components in percentage by mass: 60% of rock powder, 17% of slag, 3% of NaOH solution with the mass fraction of 30%, 12% of water glass with the modulus of 3.2 and 8% of water. The preparation method comprises the steps of proportioning, primary screening, mixing and stirring and additive mixing. According to the modified blast hole blocking material applied to strip mine blasting and the preparation method thereof, a traditional rock powder blocking material is replaced, and the modified blast hole blocking material has the advantages of being low in manufacturing cost, good in environmental protection performance and wide in source range. The material is simple in preparation step, short in maintenance time, high in early strength and capable of rapidly achieving the blast hole blocking effect and improving the blasting quality.
本发明公开了一种应用于露天矿爆破的改性炮孔堵塞材料及制备方法，属于矿山爆破技术领域。改性炮孔堵塞材料包括组分及质量百分含量为为：岩粉60％，矿渣17％，质量分数30％的NaOH溶液3％，模数3.2的水玻璃12％，水8％。其制备方法为：配比、初筛、混合搅拌和混合添加剂的步骤。本发明采用以上的一种应用于露天矿爆破的改性炮孔堵塞材料及其制备方法，替代传统的岩粉堵塞材料具有制作成本低，环保性能好，来源范围广的特点。该材料制备步骤简单，养护时间短，且早期强度高，可以快速达到炮孔堵塞的效果，提高爆破质量。
