Abstract
:In order to safely and smoothly complete the road excavation proj ect of Liantang wind farm fan adj acent to the
provincial cultural relics protection unit,based on the excavation proj ect of 25 # fan road,the mechanism of CO 2 expansion
blasting was and empirical methods for determining the hole spacing were studied,the damage
control measures and construction process were discussed and formation of the flying pipe and the filling
structure of the blast holes were emphatically application of engineering shows that the CO 2 expansion
blasting technology has the characteristics of intrinsic safety,less harm ,easy control,no spark,non-toxic gas,and low
explosive temperature,and it has a broad application prospect in some proj ects where safety requirements are high and
explosives are not suitable for can provide a useful reference for similar proj ects.
