This topic is divided into ten chapters , and illustrates cutting blasting technology which is the master influence factors of blasting technique of quick tunneling in rock drift .
This topic firstly expounds the roadway excavation status and existing problems , and the development of theory of roadway, the main factors of roadway and the research plan . Then cut blasting theory , contrast of the theory of Spherical medicine package and columnar medicine package , the blasting effect mechanism of cut blasting theory,including rock into slag mechanical motion rule, slag, physical model . Cutting type selection . Roadway excavation blasting theory include other function, air column spacing charging blasting technology, charge structure and initiation order, The latest theory - section delay blasting theory and rock damage theory . For the engineering example.
Key words: rock blasting ; crushing zone ; cast slag ; cutting type ; depth of borehole ; number of borehole ; arranging boreholes ; underwater ; jam length ; action of empty hole ; interval propellant ;initiation order ; charging structure ; delay blasting ; Rock damage
