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.
