20100300318 | Blast Hole Plugging Apparatus - Apparatus for plugging a hole, such as a bore hole used in blasting, comprises a platform shaped to fit within the hole and to support material such as explosives or stemming at a desired depth in the hole. The platform takes the form of a plate or tray which is generally ellipsoidal in shape so that it fits snugly within the hole when inclined transversely relative to a longitudinal axis of the hole. The plate has a central load support region and a peripheral region for engaging the wall of the hole. The apparatus includes a locking member, typically a length of rigid pipe, attached movably to the platform. The locking member is moveable between a first position in which it is supported clear of the wall of the hole below the platform, and a second position in which it spans the hole to lock the platform in position in the hole. An elongated actuating member in the form of a cord or line is connected to the locking member and platform for lowering the apparatus into the hole and for moving the locking member between its first and second positions. | 12-02-2010 |

20110277656 | Explosive Powder Plug and Method of Using the Same - An inexpensive bullet-shaped plug is shown for use in a blasting hole containing water in the bottom thereof, which plug permits dry powder to be used above the waterline rather than more expensive wet powder. After the blasting holes are drilled, if water accumulates in the bottom thereof, the bullet-shaped plug with a center weight is dropped into the hole, which bullet-shaped plug floats on the water. Small rocks are dropped on top of the bullet-shaped plug causing upper tentacles to flare out to engage the wall of the blasting hole. Dry powder is then loaded into the blasting hole on top of the bullet-shaped plug. A cap is inserted a distance below the surface of the blasting hole. Thereafter, a series of similar blasting holes are blown at one time to create debris that can be removed or further processed. | 11-17-2011 |

20150308796 | METHOD AND DEVICE FOR MICRO BLASTING WITH REUSABLE BLASTING RODS AND ELECTRICALLY IGNITED CARTRIDGES - A apparatus, method and system to electrically ignite small explosive cartridges in boulders, bedrock, concrete and other materials so as to split the material into smaller pieces or to shape it. To ignite the propellant or other explosive charge electrically by melting at high temperature a bridge wire(s) or bridge ribbon(s) with electrical current which can be AC or DC. The bridge melts normally at over 2,000 degrees F. which will ignite the propellant or explosive. With sufficient voltage and amperage such as standard 110 volt AC wall current ionization takes place along the pathway of the melted bridge and a large electrical arc forms that ignites the propellant or explosive with even higher certainty as electrical arc temperatures are often over 5,000 degrees F. When the propellant or explosive is ignited at higher temperature there are known beneficial effects for increased blast power. The blast with this apparatus and method is tamped with a reusable blasting rod with an external groove for a blasting wire to fit into so electrical current can be supplied to the cartridge in the borehole. The blasting rod is normally attached to a counterweight or blasting head for better tamping and has a cradle on top for rocks or other heavy objects to be placed on top for even better tamping through the Newton Kinetic effect. | 10-29-2015 |
