The invention discloses a shallow hole charging device in underground mining. The shallow hole charging device in underground mining comprises a second explosive cylinder and a push rod, wherein a first explosive cylinder is fixed on the upper part of the outer side surface of the second explosive cylinder through a fixing ring; a hemisphere is fixed on the upper part of the outer side surface of the first explosive cylinder through a fixing ring; a detonator is fixed in a mounting groove of the lower surface of the second explosive cylinder; the lower end of the detonator is connected with a wire; the lower part of the outer side surface of the second explosive cylinder and a connecting end of the upper end of the push rod are fixedly connected with each other through a fixing ring; a screw hole is formed in the lower end of the push rod; the screw hole of the push rod is in threaded connection with threads at the upper end of the connecting rod; the first explosive cylinder and the second explosive cylinder are fixed by elastic sheets to prevent the circumstance that the first explosive cylinder and the second explosive cylinder slide to affect the blasting effect; and a connecting rod is in threaded connection with the push rod so as to facilitate movement and transportation. The labor intensity of workers is greatly relieved, and the job progress is improved effectively. The method is simple, and is convenient to operate; and the charging effect is good.
Description
technical field [0001] The invention relates to the technical field of gold mining, in particular to a shallow-hole explosive charging device for underground mining. Background technique [0002] Blasting technology is often used in gold mining. Reasonable packing length and good packing quality have a great influence on the full use of explosive energy, blasting quality and safety; Differences in technology and other aspects will directly or indirectly affect the quality and time of charge, resulting in project delays and poor blasting effects, or even failure to detonate, burying hidden dangers to coal mine safety production. Contents of the invention [0003] The technical problem to be solved by the present invention is to overcome the existing defects and provide a shallow-hole explosive charging device for underground mining. The elastic sheet fixes the first explosive column and the second explosive column to prevent them from sliding and affect the blasting effect;...
