| Abstract: | The superposed blasting cone is used for excavation of a pipe ditch for gas transportation.Taking the blasting excavation of Seninglan pipe ditch with a bottom width of 1.6m and a depth of 2.4m as an example,the principle of trench formation by superposed blasting cone,the tests of blasting cone,the design of blasting parameters,charge structure and priming circuit are introduced.Besides,the blasting construction and safety check are outlined.At the same time,the result of blasting excavation is described and analyzed. |
