Problems solved by technology

[0002] During the blasting construction of horizontal layered rock, due to the particularity of its geological conditions, the rock layer is prone to lift during the pre-splitting blasting, and it is difficult for the blasting gas to cut the blast hole in a directional manner
The traditional pre-splitting blasting construction method has poor slope forming effect, and a directional blasting method is required for pre-splitting. By adopting directional pre-splitting blasting technology, the amount of explosives is reduced and the effect of horizontal rock formation pre-splitting is improved.

Abstract

The invention discloses an energy gathering groove cutting device used for a blast hole and belongs to the technical field of rock blasting construction. The energy gathering groove cutting device comprises an electromotor, a first fixed pulley and a second fixed pulley. The electromotor is connected to the first fixed pulley. A sleeve is fixed between the first fixed pulley and the second fixed pulley. A rope saw driven by the first fixed pulley is arranged in the exterior, between the first fixed pulley and the second fixed pulley, of the sleeve. The pre-splitting blasting effect and the blasting construction quality are improved, and the construction cost is reduced; and the device is simple in structure, high in maneuverability, convenient to mount and low in cost.

Description

technical field [0001] The invention relates to the technical field of rock blasting construction, in particular to an energy-gathering groove cutting device for blasting holes. Background technique [0002] During the blasting construction of horizontal layered rock, due to the particularity of its geological conditions, the rock formation is prone to lift during pre-split blasting, and the blasting gas is difficult to directionally cut the blast hole. The traditional pre-split blasting construction method has poor slope forming effect, and a directional blasting method is required for pre-splitting. The use of directional pre-split blasting technology reduces the amount of explosives and improves the effect of pre-splitting in horizontal rock formations. SUMMARY OF THE INVENTION [0003] The technical problem to be solved by the present invention is to provide an energy-gathering groove cutting device for blasting holes, which improves the pre-split blasting effect and b...
