聚能水压光面爆破在岩巷掘进中的研究

Study on Smooth Blasting by Shaped Water Pressure in Rock Roadway Excavation

由于爆破技术在社会中的快速发展,聚能水压光面爆破技术开始在隧道开挖、巷道掘进等其他工程中逐渐应用。根据呼和乌素煤矿在岩巷掘进中的情况,通过对比常规光面爆破技术,从而体现出聚能水压光面爆破技术在其装置设备和原理上的优势。减少了炮孔的数量,降低了钻孔的费用,提高了岩巷掘进速度,减弱了围岩震动速度,实现了"三提高,一保护"的作用。在类似的岩巷掘进工程中具有借鉴的意义。

Due to the blasting technology developed quickly in society, shaped water surface blasting technology has gradually been applied in tunnel excavation and rock roadway excavation or other projects. According to the situation of Huhewusu coal mine in rock roadway excavation, the advantages of the combined hydraulic blasting technology in principle and device are highlighted by comparing the conventional smooth blasting technology. The number of holes is reduced and the cost of drilling is reduced. It improves the speed of rock drift driving and reduces the vibration velocity of surrounding rock has been reduced, and it has the function of "three improvements and one protection". It has reference significance in similar rock roadway works.
