薄层状青云石矿的切割爆破技术
Blasting Technology of Cutting Thin-Layer Qingyun-Stone
-
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。
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 can 't be used to cut this stone , and its blasting technique needs further experimental studies .
