小型露天采石场中深孔爆破方案优化设计

钻孔爆破方式的选择是采矿成本高低的一个重要制约因素。通过调研绵阳地区部分小型露天采石场使用的中深孔爆破的方案,分析并指出其在爆破质量、生产安全性能和效率方面存在的不足之处,根据矿体赋存条件和实际生产状况对该中深孔爆破方案进行了重新设计,并进行了矿山现场实践,在安全生产和经济效果方面取得了良好的效果。研究成果可用于小型采石场。

Optimization Design of Medium-length Hole Blasting in Small-scale and Opencast Quarry

Achieve higher efficiency is a aim of mining enterprises on the basis of safety produce,choice of the blasting method is an important restraining factor about mining costs.The deficiencies of medium-length hole blasting in small-scale and opencast quarry of Mianyang area were analyzed and pointed out by detailed survey.The suitable method of medium-length hole blasting in small-scale and opencast quarry of Mianyang area were designed according to deposit condition of mine and production status.It achieved good results on safe production and economic efficiency by carrying out the design.The optimization design can promote and improve small Small-scale and opencast quarry safety in production and economy efficiency.
