Abstract

The present disclosure relates to the technical field of blasting, in particular to a multi-split instant expander. The multi-split instant expander includes: a multi-split slit pipe, the wall of the multi-split slit pipe is provided with a plurality of energy-gathering areas arranged at intervals in the circumferential direction, and the energy-gathering areas include multiple energy gathering holes arranged at intervals in the axial direction of the multi-split slit pipe, wherein the multiple energy gathering areas include multiple pairs of energy gathering areas, and two of each pair of energy gathering areas are located on the multi-split plane The slit pipes are arranged opposite to each other in the radial direction; the expansion parts are arranged in the multi-split slit pipe. The multi-crack surface instantaneous expansion device provided by the present disclosure has the advantages of multi-crack surface expansion, high safety, good expansion effect, low rock-breaking noise and low manufacturing cost.

Description

technical field [0001] The present disclosure relates to the technical field of blasting, in particular to a multi-split instant expander. Background technique [0002] At present, geotechnical engineering such as hard roof and hard top coal weakening in coal mines, tunnel drilling and blasting, and boulder treatment in roadbeds all need to form multiple cracks in the rock mass. However, the use of traditional explosive rock breaking technology has a series of problems such as difficulty in approval, high transportation risk, difficulty in controlling blasting energy, high noise, and uncontrollable number and direction of splitting surfaces. Therefore urgently need to find the substitute of explosive. [0003] It should be noted that the information disclosed in the above background section is only for enhancing the understanding of the background of the present disclosure, and therefore it may include information that does not constitute the prior art that is already known...
