秦皇岛输油首站罐区内两台10万 m~3油罐,是我国首次建设的最大金属油罐,位于原15~#罐北侧。为建这两座油罐,拆除了原有两万 m~3半地下式非金属油罐(16~#)一座,搬走北侧一座山包,共开挖和运输土石23万 m~3,这些土石系由炸药爆破开挖,汽车运输倒入附近山沟内。由于采取了一系列安全措施,从1985年3月开工到6月完工,实现了安全施工,圆满地完成任务。现对罐区内爆破的安全问题作简要总结。一、确定爆破的安全界限新建的两座10万 m~3油罐(新1~#、新2~#)周围,共有15座油罐(总容量30万 m~3)正在使用.而开挖边线离正在使用的15~#罐最近处仅
Qinhuangdao first tank station two 100,000 m3 oil tank, is China’s first construction of the largest metal tank, located in the original 15 ~ # north of the tank. For the construction of these two oil tanks, one of the existing 20,000-3,000 underground non-metallic oil tanks (16 ~ #) was demolished and a mountain bag was removed on the north side to excavate and transport 230,000 m3 of earth and rock. These earth and rock excavation by explosives, motor transport into the nearby ravine. As a result of a series of security measures, starting from March 1985 to June completed, to achieve a safe construction, successful completion of the mission. At present, the safety of blasting in the tank area is briefly summarized. First, to determine the safety margin of blasting The new two 10 million m ~ 3 tanks (New 1 #, New 2 ~ #) around a total of 15 tanks (total capacity 300,000 m ~ 3) are in use. Excavating the edge of the 15 ~ # tank is being used only recently
