深孔台阶松动爆破技术在矿区岩石开挖中应用分析

Application and Analysis of Deep-hole Step Loose Blasting Technology in Rock Excavation in Mining Area

根据矿区周围岩石状况、地质层分布特点以及爆破工程量的估算,认为多种岩石结构下深孔台阶松动爆破适用于周边环境复杂、爆破安全警戒影响因素较多的矿区土石方爆破工程。结合新疆地区某复杂矿区环境、多种岩石结构下深孔台阶松动爆破技术特点,进行爆破网络设计和爆破参数选取,并进行爆破安全设计和防护等,提高了爆破效果和工作效率,带来了较好的社会及经济效益,对同种类型工程设计与施工具有参考价值。

According to the rock condition around the mining area,the geological layer distribution characteristics and the estimate of blasting engineering quantity,it is considered that the deep hole step loose blasting under various rock structures is suitable for the earthwork blasting project in mining area with complicated surrounding environment and many factors influencing blasting safety. Combining Xinjiang region under a certain mining area environment,a variety of complex rock structure loose of deep hole bench blasting technology characteristic,network design and the selection of blasting parameters for blasting,and blasting safety design and protection,etc.,to improve the blasting effect and work efficiency,and brings good social and economic benefits,have reference value for the same type of engineering design and construction.
