Description

Technical Field

[0001] This utility model belongs to the technical field of blasting construction equipment, specifically relating to a device for compacting drill cuttings after filling blast holes. Background Technology

[0002] In engineering fields such as mining, tunneling, and earthmoving blasting, borehole blasting is a widely used technique. To ensure blasting effectiveness, prevent premature leakage of explosive gases and control flyrock, and reduce blasting vibration and noise, the borehole must be effectively sealed after loading the explosives. Traditionally, drill cuttings, clay, or special stemming material are used for sealing, forming a "stemmed" section with a certain density and length. The density of the stemming material is a key factor in the sealing effect; insufficient density will lead to reduced utilization of explosive energy, poor blasting effect, and even serious safety accidents.
