摘要:
根据露天台阶爆破粉尘的产生和扩散机制，提出了适用于大型露天台阶爆破的水雾和泡沫降尘技术。通过现场试验，完善了水雾和泡沫发生装置，获得了爆炸成雾合理的爆炸能及延期时间等参数。该技术在缅甸莱比塘矿山大规模露天爆破中得到应用，测得露天台阶爆破粉尘的质量浓度降低了43.0%～49.5%，炮烟体积降低了50%，露天矿台阶爆破降尘效果非常明显。这对减少爆破雾霾、降低环境污染具有重要的作用。
Abstract:
According to the generation and diffusion mechanism of explosion dust in open-pit beach blasting, a dust suppression technology with spray and foam used in large-scale open bench blasting was proposed. Spray and foam generator was improved by field test. Reasonable parameters, such as explosion energy and delay time, were characterized. This technology was applied in large-scale open bench blasting of LPD mines. Results show that the dust concentration has been reduced by 43.0%~49.5%, and the volume of cannon was 50% lower than before. Dust reduction of this technology used in beach blasting of open-pit mine is obvious. And it has an important role in reducing blasting haze and reducing environmental pollution.
