摘要
为减少大块率和根底,提高爆破效果,山西桃园东义水泥有限公司石料生产线通过理论计算和现场试验,取得了大孔距小排距技术在中深孔爆破中的一些应用经验。当孔距为4.8m,排距为3.5m时,爆破效果良好。
In order to reduce the boulder yield and bedrock and improve blasting effect, stone production line of Shanxi Taoyuan Dongyi Cement Co. ,Ltd. used theoretical calculations and field test, gain some experiences about the application of large hole spacing-small row spacing in medium-length hole blasting. When the hole spacing is 4.8 m while the row spacing is 3.5 m,the blasting effect is good.
