摘要： An elastomeric blasting plug and method of using the same are described. The elastomeric blasting plug may include a plurality of stacked units that taper from a base to a stem. A fuse may extend through the elastomeric blasting plug and the elastomeric blasting plug may expand radially after detonating the fuse and explosive charge.

摘要： A stemming plug (10) for stemming a blast hole in a mine, the plug (10) comprising an active wedge-shaped member (12) having a sloping face received in sliding relationship with a matching face of a passive wedge-shaped member (14). In use, the active wedge-shaped member (12) is positioned nearest to an explosive material in the blast hole and the passive wedge-shaped member (14) is positioned further from the explosive material in the blast hole. The active wedge-shaped member (12) has a friction reducing material provided on at least part of its surface to reduce the sliding resistance of the active wedge-shaped member (12) relative to the passive wedge-shaped member (14); whereby, in use, when a shockwave from initiation of the explosive material in the blast hole encounters the active wedge-shaped member (12) it acts as a piston, sliding on the passive wedge-shaped member (14) so that both wedge-shaped members exert diametrically opposed forces against a wall of the blast hole and are locked in place.

摘要： In a seal device for a hydraulic circuit, in which an oil passage that supplies hydraulic oil to or discharges the hydraulic oil from a hydraulic actuator operated by hydraulic pressure is formed over at least two members that relatively move, and a seal member that seals a gap between the two members in a liquid-tight manner is disposed in an interior of a groove section that is formed in at least either one of the two members, a communication section that allows the groove section to communicate with any portion of the oil passage such that the hydraulic oil in the interior of the groove section moves along with supply of the hydraulic oil to or discharge of the hydraulic oil from the hydraulic actuator is formed.

摘要： 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.

摘要： A conical plug for sealing a blast hole in the earth is provided. The plug is made from a generally circular sheet of elastic material such as plastic or metal and can be folded and releasably locked with a trigger into a conical shape. When in its conical shape, the plug is lowered into a blast hole and, when in position, a release weight is slid down the lowering cable to impact and release the trigger. When the trigger is released, the plug expands and is wedged against the sides of the blast hole forming a plug capable of supporting debris in the upper portion of the blast hole.

摘要： A mine shaft closure plug which is created by a self-expanding plastic foam on a platform positioned within the mine shaft. Multiple expansion foam containers are used to provide the foam. Each expansion foam container has two closed waterproof pouches, an inner pouch and an outer pouch, each containing a separate component of the foam. The inner pouch is contained within the outer pouch. Upon breaking the inner pouch, the separate foam components combine within the outer pouch to form a complete expansion foam. The foam expands slowly enough to provide sufficient time for the container to be placed on the platform. Once in position, the expansion foam bursts the outer pouch to form the expansion foam plug above the platform. Either the platform or the expansion foam containers may be lowered into place by attached tethers.

摘要： Inflatable devices configured for use particularly in large diameter boreholes and in blasting applications such as vertical cratering, the invention finds utility in blast removal of earth formations wherein the inflatable devices act to suspend explosives and/or stemming materials and the like within a borehole prior to detonation of explosives within said borehole. The inflatable devices are of various shapes and comprise an inner, relatively stretchable inflatable bag enclosed by an outer, relatively non-resilient bag, the inner bag having a valve to allow a fluid such as air to be pumped thereinto with the inner bag expanding to contact inner walls of the outer bag and force the outer bag into contact with walls of the borehole to exert forces against the borehole walls and thus "plug" the borehole at a desired location along the length thereof. Explosive materials and/or stemming materials can thus be suspended at desired locations within the borehole.

摘要： A bridging plug for a circular blast hole has a relatively longer major axis and a relatively shorter minor axis. The plug is hinged to pivot about the minor axis. A tension line is secured to the minor axis for lowering the plug into an explosive placement hole. The plug pivots into an angular open position when lowered into the hole. An upward force on the tension line jams the hinged portions of the plug in a closed position to plug the hole. An explosive charge can be placed in the hole at the location defined by the closed plug.
