【摘要】 工程微差爆破最近40年来控制爆破发展的新技术,它使工程爆破的使用领域得到拓展,原先只能在矿山或人烟稀少,远离建筑物地区进行的爆破施工,现在,即使在人口稠密、楼房鳞次栉比的城镇,甚至建筑物内部都有可能实施控制爆破。它减轻了劳动强度,缩短了施工期限,降低了工程成本。因此,正确的计算方法具有较大的经济效益。更多还原

【Abstract】 Engineering small deviation of blasting the past 40 years to control the burst of development of new technologies which enable the project to the use of blasting the area to be expanded,the original only in the mines or sparsely populated areas away from the blasting of the building construction,and now,even in the population dense,row upon row of buildings,towns,and even inside Buildings are likely to exercise control blasting.It reduced the labor intensity,shorten the construction period,reduce the cost of the project.Therefore,the correct method of calcrlation have greater economic benefits.更多还原
