摘要:
针对晋宁磷矿目前所采用的中深孔爆破设计方法存在钻机效率发挥不足，单方岩石钻机柴油消耗达不到要求的问题，以及考虑对矿体围岩爆破成本进行有效控制，提出一种新的穿孔爆破技术设计方法，以提高钻机效率，降低单方岩石钻机柴油消耗和穿爆破成本为目的.在岩石性质、地质条件、铲装设备及爆破技术条件满足的前提下，采取延长炮孔钻凿深度，增大爆破台阶高度，然后根据孔径、台阶坡面角计算确定炮孔孔网参数，再结合岩石性质调整单孔装药量，在确保安全的基础上提出了15 m深孔爆破技术设计方案.研究数据表明:与原爆破技术比较,钻机效率提高了50.74%, 单方岩石钻机柴油消耗从0.053 kg/m3下降到0.033 kg/m3,柴油消耗控制在0.035 kg/m3以内.
Abstract:
The design of mediumlength hole blasting method used in Jinning phosphate rock has insufficient drilling efficiency, and a cubic rock drilling rig diesel consumption does not meet the requirements .To control effectively the surrounding rock blasting cost, a new blasting technology was put forward to improve the efficiency of drilling rig, reduce the consumption of the diesel rock drill blasting costs and wear. Under the conditions of rock properties, geological conditions, shovel loading equipment and blasting technology meeting the requirements, the depth of hole drilling was extended, the height blasting bench was increased, and then the hole pattern parameters were determined according to the calculated the aperture, slope angle; each hole explosive quantity was adjusted combined with rock properties, and the 15 m deep hole blasting technology design was put forward on the basis of safety. Research data indicate that compared with the original blasting technology, rig efficiency is increased by 50.74%, the drill diesel consumption is reduced from 0.053 kg/m3 to 0.033 kg/m3,the diesel consumption control is in 0.035 kg/m3.
