薄层状青云石矿的切割爆破技术

对于薄层状青云石矿，密集的、强度较低的层理面严重影响切割爆破效果，不能沿用块状石材的切割爆破方法，因此需要进一步试验研究。在分析薄层状青云石矿强度特征和层裂破坏特性的基础上，对其进行了分离爆破和分割爆破试验。试验结果表明，只要采取合理的爆破参数和技术措施，对薄层状矿石同样可以获得良好的切割爆破效果。

Blasting Technology of Cutting Thin -Layer Qingyun- Stone

For thin - layered Qingyun - stone ore, the dense and lower strength bedding faces influence greatly the effect of cutting blasting, so the cutting blasting technology for massive stone cant be used to cut this stone, and its blasting technique needs further experimental studies. On the basis of analyzing strength and layer - crack damage characteristics of thin - layered Qinyun -stone ore, the separate blasting and cutting blasting tests are carried out on it. The results indicate that good cutting effects can be achieved if reasonable blasting parameters and technical measures is used for blasting thin - layered Qinyun - stone ore.
