摘要
安家岭露天矿东帮靠界区周边有大量的土坯房、停车场、井工矿地下巷道等建筑物,为了解决爆破有害效应对周边建筑物的影响,结合周边情况和现场已有的穿孔和采装设备,制定出一套专项爆破施工方案,专门用于靠界区爆破施工。结果表明:该套专项爆破施工方案在满足生产正常接续的同时,没有对周边建筑物造成任何的安全问题。
There are a large number of adobe houses,parking lots,underground roadways and other buildings around the eastern boundary area in Anjialing Open-pit Mine.In order to solve the impact of blasting harmful effects on surrounding buildings,at the same time,we combine with the surrounding conditions and the existing perforation and mining equipment on site,formulate a set of special blasting construction scheme,which is specially used for the blasting construction near the battery limit.The results show that the set of special blasting construction scheme can meet the normal connection of production,and not cause any safety impact on the surrounding buildings.
