摘要： The present disclosure relates to a blasting device for simultaneously registering multiple detonators based on blasting pattern information and a method of using the same, and the blasting device includes a blasting pattern information input unit that receives blasting pattern information about a blasting operation to be performed to store the received blasting pattern information, a key value sharing unit that shares a key value with a tracker possessed by an operator when the tracker is activated, a blasting area entry recognition unit that recognizes at least one communication module and tracker that are activated in a blasting area, and a detonator registration unit that registers multiple detonators by using the number of the at least one communication module and tracker recognized in the blasting area and pre-stored blasting pattern information.

摘要： A block cave has a draw column height of at least 450 m, a caved volume, a single extraction level and noundercut level, a plurality of drawbells extending upwardly from the extraction level to the caved volume, and a plurality of pillars separating the drawbells and supporting the rock mass above the extraction level. Each drawbell has a drawbell height of at least 25 m. Each drawbell has the following profile when viewed from a direction perpendicular to a drawbell drive in the extraction level: a throat section having opposed parallel side walls extending upwardly from the extraction level, a tapered section above the throat section, and an undercut section above the tapered section.

摘要： A tunnel section subjected to grouting reinforcement is divided into two parts, that is, an upper half section and a lower half section, cutting vibration reduction holes used in coordination with cutting holes are formed in the upper half section, and the cutting vibration reduction holes are not charged and are filled with water bags only. According to the blast hole arrangement structure used for blasting for the rheological soft-weak surrounding rock tunnel of the invention, a cutting blasting effect is improved, excess energy is emptied and absorbed, propagation of shock waves and stress waves around is reduced, and vibration is reduced; and according to the invention, the purpose of forming vibration isolation holes in a tunnel excavation contour line of the upper half section is to prevent, absorb, reflect and refract the propagation of the blasting shock waves, stress waves and seismic waves.

摘要： The invention provides an apparatus and method for preventing surrounding loose rock fragments from falling or collapsing into a blast hole. The apparatus includes a flexible sheet including a pair of spaced apart longitudinally extending side edges and a pair of spaced apart laterally extending end edges. The sheet has a curved form defining a longitudinal passage extending between openings at longitudinally opposite ends, one end of the curved sheet being insertable into the open end of a blast hole whereby the curved sheet closely faces an internal surface of the blast hole and forms a barrier preventing surrounding loose rock fragments from falling or collapsing into the open end of the blast hole. The invention also provides a bench blasting method and a deployment device for deploying the apparatus into a blast hole.

摘要： A system and apparatus for plasma blasting comprises a borehole, with a novel blast probe, the probe comprising a high voltage electrode and a ground casing tube with a ground and/or electrode deflector. The ground and/or electrode deflector focuses a plasma blast through openings in the probe, directing the blast force away from the ends of the probe, wherein at least a portion of the high voltage electrode and the ground electrode are submerged in the blast media. The blasting media comprises water alone or in combination with other materials. The robust blast probe permits the aiming of the blast outside of the probe.

摘要： Apparatus and methods for preparing a blast hole in a rock face during a mining operation are disclosed. An exemplary method comprises: deploying a first tool toward the blast hole in the rock face via a common tool outlet of a feed unit using a first tool station of the feed unit; retracting the first tool from the common tool outlet using the first tool station of the feed unit and retaining the first tool in the first tool station; and while the first tool is retained in the first tool station, deploying a second tool toward the blast hole in the rock face through the common tool outlet of the feed unit using a second tool station of the feed unit.
