NOTHING HEREIN IS TO BE REGARDED AS INDICATING APPROVAL OR DISAPPROVAL OF ANY SPECIFIC PRODUCT OR PRACTICE. 2 FOREWORD This manual is designed primarily as a text to be used in the teaching of basic rescue procedures to be used following accidents at surface and underground mining operations. It will also serve as a guide to good practices at any time when people are in a physically dangerous situation and must be moved to a safe place. Mine rescue work is demanding and at times dangerous. Mine rescue teams are highly trained and skilled personnel. They must have an intimate knowledge of their equipment and master all the skills required to accomplish their rescue missions, although they may never be required to put their training to use. In fact, only a small percentage of miners who have received mine rescue training will ever be called upon for actual rescue work. Nevertheless, if the need should arise, rescue teams will be ready to go to the aid of their fellow workers. It is also most important that mine officials receive periodic instruction and training in the duties they will be required to perform, both individually and collectively, in the event of a mine disaster at their operation. The mining laws of British Columbia require that trained mine rescue personnel and mine rescue equipment be maintained at all mines. To this end, basic mine rescue training courses are conducted at mining properties so that miners will have an opportunity to learn the skills required of the mine rescue team. Once the basic skills are learned, many hours of training and practice are needed to develop a competent mine rescue team that can work together and, with other teams, accomplish rescue objectives in the event of a mine disaster. On several recent occasions British Columbia mine rescue teams have been called upon to assist in disasters both in the province and in other areas. It is a tribute to the skill, training and courage of these men that they have always done their job in an exemplary way which has brought praise and recognition for their efforts. The Mine Rescue Certificate and the “MINE RESCUE” sticker on your hard hat are things to be proud of as they tell the world that you are concerned and that you really care about your fellow workers. You care to the extent that you have been willing to devote many hours of study and practice to learn the skills required of a mine rescue team. Douglas E. Sweeney, Chief Inspector of Mines, Ministry of Energy, Mines and Petroleum Resources. iii TABLE OF CONTENTS FOREWORD ...................................................................................

    Trench Blasting with DYNAMITE A TRADITION OF INNOVATION Dyno Nobel’s roots reach back to every significant in- novation in explosives safety and technology. Today, Dyno Nobel supplies a full line of explosives products and blasting services to mines, quarries and contractors in nearly every part of the world. DYNAMITE PRODUCT OF CHOICE FOR TRENCH BLASTING One explosive product has survived the test of time to become a true classic in the industry. DYNAMITE! The dynamite products manufactured today by Dyno Nobel are similar to Alfred Nobel’s original 1860s invention yet, in selected applications, they outperform any other commercial explosives on the market. The high energy, reliability and easy loading characteristics of dynamite make it the product of choice for difficult and demand- ing trench blasting jobs. Look to Unigel®, Dynomax Pro® and Unimax® to make trench blasting as effective and efficient as it can be. DISCLAIMER The information set forth herein is provided for informational purposes only. No representation or warranty is made or intended by DYNO NOBEL INC. or its affiliates as to the applicability of any procedures to any par- ticular situation or circumstance or as to the completeness or accuracy of any information contained herein.

  • DITTMAR V. RIX and ANOTHER. Circuit Court, S
    DITTMAR V. RIX AND ANOTHER. Circuit Court, S. D. New York. March 13, 1880. PATENT—COMPOUND MADE BY PATENTED PROCESS.—A patent containing two claims, the one for a certain process set forth, and the other for a certain compound made by the process set forth, is not infringed by the manufacture of a similar compound, not made by the patented process. Motion for preliminary injunction to restrain the infringement of letters patent. Everett P. Wheeler and Clarence Lexow, for plaintiff. George Gifford and Causten Browne, for defendants. BLATCHFORD, J. This is a motion for a preliminary injunction to restrain the infringement of letters patent granted to the plaintiff, January 18, 1870, for an “improvement in explosive compounds.” The specification states that the patentee has invented an explosive agent which he calls “Dualin, and which is to be used instead of other explosive agents, such as powder, gun-cotton, nitro-glycerine, dynamite, etc.” It proceeds: “Dualin is a yellowish brown powder, resembling in appearance Virginia smoking tobacco. It will, if lighted in the open air, burn without exploding; but, if confined, it may be made to explode in the same manner as common 343 powder. It is not sensitive to concussion, will not decompose by itself, not cake or pack together, may be readily filled into cartridges, and it matters not whether the place where it is stored be warm or cold, dry or damp. Dualin has from four to ten times the strength of common powder, and is stronger than dynamite, an improvement on nitro-glycerine. Some of the

  • 1 English 467 Professor Anne Fadiman by Submitting This Essay, I
    English 467 Professor Anne Fadiman By submitting this essay, I attest that it is my own work, completed in accordance with University regulations. Paul Gleason Breaking Rock by Paul Gleason Dino pulls a brass plunger, thick as a screwdriver, off his belt and punches a hole in the yellow-tissue-covered stick of dynamite. He then replaces the plunger with a small cylindrical blasting cap. The late October cold makes the Blasting Gelatin stiff, he explains, raising his voice over the sound of shattering rock coming from under Donnie’s drilling machine. If he tried to shove the blasting cap right in, it might break, and if it broke—“all over,” he says, grinning broadly and waving a hand in circles around his face and chest. “Blood and guts all over you.” Together, the blasting cap and dynamite make a charge. The cap connects to an orange “shock tube,” full of a powder that burns at a rate of three miles per second. Several charges linked together make a shot. Dino drops the charge down one of Donnie’s thirteen-foot holes, letting the tube run between his fingers until it goes slack. He picks up the sixteen-foot-tall pole lying on the ground; it has black circles and numbers marking every foot. He steadily lowers it into the hole and taps the dynamite into place. This is the first of eight holes, eight charges that will go off as one shot. Cox Drilling and Blasting, Dino and Donnie’s employer, is one of several companies working at 18 Temple Street, a 200’-by-100’ lot in the middle of downtown Hartford.

  • Chapter 6 INITIATION
    Chapter 6 INITIATION COMPONENTS USED IN ELECTRIC BLASTING The electric power source used to initiate a blast may be a twist or push type generator blasting machine and a remote radio device, a condenser discharge machine, or an AC power line through a blasting switch. Never use batteries directly; only a blasting machine or blasting switch provides the current and time control necessary to prevent cap arcing and misfires. The generator type blasting machine converts the mechanical energy of the blaster’s hand motion into electrical energy and then closes the contacts to the firing circuit when the peak electric energy is generated. A condenser discharge machine uses dry-cell batteries to charge a set of capacitors. When the fire button is pushed, the stored electrical energy in these capacitors is discharged into the firing circuit. The remote detona- tion system can be activated and controlled with the commonly used King radio that has been retrofitted with a dual tone modulated frequency chip (DTMF). The entire remote detonation system allows the blaster-in- charge more flexibility in selecting a location to initiate the blast. No alterations or repairs of an electric blasting machine should be attempted, unless by the manufacturer. Ordinary maintenance by the blaster should be limited to changing the batteries in the condenser discharge type machines and to lubricating the moving parts in the generator type. The LEAD WIRE, or the FIRING LINE as it is sometimes called, connects the power source to the blasting circuit. It should be a two-conductor, insulated, solid copper wire (with exception of the multiconduc- tor cable for a sequential blasting machine) and be at least 14-gauge thickness.
