Methods and Practices of Cost Reduction for Open Deep-hole Bench Millisecond Tight Blasting
In an open deep-hole bench millisecond tight blasting, drilling costs make up a large proportion of costs of earth work, which is the second most costly procedure after transporta tion.In this essay, open deep-hole bench millisecond tight blasting will be used as an example to propose concrete measures of improvement for blasting process and to introduce practical meth ods of charging and sealing in construction site into earth fiat work.These measures have been proved to be effective, that they can help control blasting costs, reduce blasting expenditures and bring enterprises economic benefits.
