浅析垂直扇形中深孔爆破的主要技术措施

Simply Analying the Main Technique Measures of Vertical Fan-shaped Medium-length Hole Blasting

矿山地下开采矿石,必须经过凿岩和爆破来破碎岩石。坑下采矿所采取的爆破方法与矿体围岩地质性质、采矿方法有紧密联系。根据工作实践,针对铜山铜矿垂直扇形中深孔爆破的主要技术措施,从安全技术角度进行分析和总结。

The underground ore must be exploited by drilling and blasting,the blasting method usually associated with the geologic property and the mining method of wall rocks.According to the production practice,the main technique measures of vertical fan-shaped medium-length hole blasting were summed up and analyzed from the perspective of safety.
