摘要
大塘矿井下爆破一直采用人工装药方式,作业效率低、劳动强度大、安全风险高。井下混装炸药车装药技术已比较成熟,通过对现场混装乳化炸药进行矿山巷道掘进爆破实验,实验结果表明使用现场混装乳化炸药具有很高的安全性,为混装乳化炸药在大塘矿的全面推广应用提供了实验依据。
The underground blasting in datang mine has always adopted the method of manual charging. Through the blasting experiment of mine roadway excavation with on-site mixed emulsion explosive, the experimental results show that the use of on-site mixed emulsion explosive has high safety. Compared with manual charging method, it has the advantages of low comprehensive blasting cost, providing experimental basis for the comprehensive promotion and application of mixed emulsion explosive in datang mine.
