Abstract

The invention discloses an underground explosive blasting construction method. The underground explosive blasting construction method includes following steps: preparing matrix transportation: transporting a matrix to an operation site; arranging holes and designing explosive charge of each single hole; drilling the holes; completing coupling filling for mixed explosives on the operation site; placing an initiation device; and igniting the initiation device. The underground explosive blasting construction method can add the emulsion matrix which is mixed on an earth station into a site explosive loader, adds an sensitizing agent and performs explosive loading operation on the site, completely improves safety control level, adopts a novel explosive packing and transportation mode to achievecontinuity of mechanization operation, and thereby achieves continuous filling of a large quantity of the explosives, and achieves loading mechanization. Additionally, the interior of a whole transportation pipeline does not have concave-convex portions due to internal treatment performed on connection portions of the transportation pipeline, diameters of the transportation pipeline reach consistency, transportation resistance in the transportation pipeline is reduced, loading radius is greatly enlarged, and simultaneously the mixed explosive filling operation can be achieved for places wherevehicles cannot reach, the number of employees is reduced from a hundred or more in traditional work to ten or more, and essential safety is comprehensively improved.

Description

technical field [0001] The invention relates to the field of engineering blasting, in particular to an underground explosive blasting construction method. Background technique [0002] With the popularization of mechanized charging and on-site explosive mixing technology, breakthroughs have been made in the safety level and mechanization of blasting engineering. With the improvement of the world's scientific and technological level, it is an inevitable development trend to use mechanical automation equipment for blasting engineering. As an important link in mining, blasting is an important part of mining. The charging operation is completely manual charging, which is the "short board" of mining equipment automation. Its backwardness Greatly affected the development of mining technology. At the same time, the existing downhole blasting has the characteristics of small amount of charge per hole, large number of drilling holes for a single initiation, large total amount of cha...
