1 工程概况白龟山水库管理局在新办公院场地开挖时,遇到大块体震旦纪石英岩,挖掘机械无能为力,人工开挖难度大,而且用时较长。如果采用炸药爆破,对附近建筑物、民房、高压线路将有较大影响,且造价较高。最后经过工程技术人员论证,采用静态爆破解决了问题,并达到了较好的效果。2 静态爆破的特点它具有无震动、无飞石、无噪音、无毒气污染,安全性高,破裂程度较易控制,造价较低等优点。它广泛应用于开采大理石、花岗岩和玉石等贵重石材,以及拆除各类混凝土道路、基础桥
1 Project Overview Baiguishan Reservoir Authority excavation site in the new office, encountered large blocks of Sinian quartzite, mining machinery powerlessness, artificial excavation difficult, but also with a longer time. If using explosive blasting, it will have a greater impact on nearby buildings, houses and high-voltage lines, and the cost will be higher. Finally, after engineering and technical personnel demonstration, static blasting solved the problem and achieved good results. 2 characteristics of static blasting it has no vibration, no flying stones, no noise, non-toxic gas pollution, high security, easier to control the degree of rupture, lower cost and so on. It is widely used in the mining of marble, granite and jade and other precious stones, as well as the demolition of various types of concrete roads, the basic bridge
