Abstract

The invention belongs to the technical field of blast charging and particularly relates to a convenient blast hole stemming device mainly composed of a handle, a bottom cover, a sleeve, a threaded rod, a buckle, a dowel bar base, a dowel bar, a disk and a tray. The convenient blast hole stemming device is characterized in that the tray is drawn from the sleeve and is built on a blast hole, a blast line is fixedly arranged on the tray, a stemming material is placed on the tray according to design length, the sleeve is fixed, the handle is rotated, the dowel bar base is pushed to advance under the rotation action of the threaded rod to drive the disk to advance to further push the stemming material to enter the blast hole, the handle is reversely rotated, the disk is retreated into the sleeve, the tray is pushed into the disk, and thus, the operation of blast hole stemming is completed. The convenient blast hole stemming device is simple in structure, convenient to use and capable of improving the operation precision of stemming and the stemming quality, reducing the manual labor intensity, also increasing the stemming efficiency, improving the blasting effect, increasing the utilization ratio of an explosive and reducing the construction cost.

Description

technical field [0001] The invention belongs to the technical field of blasting charges, and in particular relates to a convenient blasthole plugging device. Background technique [0002] In the construction of underground engineering and the blasting and excavation of coal mine roadways, the drilling and blasting method is still a relatively common method for hard rock. One of the most important factors affecting the effect of the drilling and blasting method is the blockage of the blast hole. The quality of blast hole plugging directly affects the rock-breaking effect. In order to reduce the temperature and pressure of the explosive gas escaping, the thermal efficiency of the explosive can be improved. In order to ensure that the explosion energy of explosives is used for rock breaking as much as possible, and to prevent energy leakage and waste, it is necessary to block the blast hole, and the length of the blockage is designed according to the blasting site. If it is no...
