Show UTAH'S GREAT CAMP. David Keith aud Thomas Kearns, veteran mining men from Utah's greatest camp, aro In the city. They came down from the Park last evening. To a Times reporter Mr. Kearns stated that the new hoisting worKS, which arc among tbe largest of the camp, of the Silver King are nearly completed. The ig engine for the works will bo In operation on the. first of the coming month. This piece of machinery is classed among the finest in the te rritory aud has a capacity second to none iu Park. The Silver King lode is a member of the Mayflower body of mines and is rich in mineral-bearing ores. "Mining is looking up In Park City " said Mr. Kearns. "We are shipping the usual amount of ore from the Mayflower, and if Bi'.ver were only at the standard Park City would bo the best mining camps in the Western country." Mr. Kearns was accompanied by Mr. M. M. Sullivan, a capitalist from Omaha, Neb., who is interested in mining aud is here looking look-ing over the field, with the possibility of investing in-vesting some of his loose money in Utah mines. Electricity In Mining. Australia, always well abreast when not ahead of older countries iu the application of the most scientific and modern appliances to the working of its industries, is rapidly waking up to tho value of electricity as a motive power for mining purposes; ausl mining engineers are giving their serious attention to electrical power. Our illustrations illustra-tions show an important instance of the adoption of electricity to mining. In these pictures the; plaut laid down a few years ago at the Phanix gold mine, Skipper's reef, Lake Wakatipu, New Zealand, are shown. The rapid development develop-ment of this mine outgrew the available water power, of which at a distauce of abont three miles there was an abundant supply; all that was necessary was to transmit this power. After consideration it was decided to erect an electrical apparatus sufficient to work a battery of twenty stamp-heads, and a dynamo motor and two large dyamo machines as the generators were erected. The house where the generators are situated situ-ated is two miles up the left hand branch of Skipper's creek, and is au iron building Co feet by 20 feet, and it is built on the base of a cliff 200 feet high, by which a fall of ISO feet is obtained, the water being carried down the cliff by two pipes, twenty-two inches in diameter at the top, and taperinsr down to six iuches nt the bottom. Two 1'eltou water wheels drive the generators. Thesi; wheels consist of a cast-iron pulley or fly wheel having square-shaped brackets around its periphery. A nozzle two and one-half iuches in diameter diam-eter throws a powerful jet of water in these buckets, causing the wheel to make 370 revolutions rev-olutions per minute. When workiug at its full power, each wheel is capable of exerting lifty-horse power. The generators are driven from the wheels by means of counter-shafting counter-shafting aud belting, and the whole machinery is secured to heavy timber foundations. The two generators are driven at a speed of from TOO to 800 revolutions revolu-tions per minute, and generate a current of ten amperes with a pressure of 2000 volts, but being coupled in parallel their current capacity is twenty amperes. The current goes to a switchboard and an ammeter ia placed In the circuit. The current cur-rent is conveyed from the generating station to the battery house aud back by a So. 8 B. W. G. copper wire, nearly six miles in lenjrth, supported by telegraph poles, and brought over a hill about 600 feet iu height, between the generating station and the battery bat-tery house. The power loft in the line is only three-horse power, and this could be " reduced by using larger wires. Lightning arresters protect the generators and motors. The Victoria motor, working under normal nor-mal conditions, makes about 350 revolutions per minute, and the pulley on the armature shaft transmits the motion by means of a belt to the cam shaft of the bnttery. The amount of the current sent through the motor is regulated by a switch so that the power developed can be exactly regulated to meet all requirements; when the motor Is stopped for any purpose, aud it is not necessary neces-sary to stop the generator, the current is switched oil the motor to a series of iron wire coil?.. The battery of staiupheads, which weigh 800 pounds apiece, starts easily and can be topped in?tantaueouoly. A man is told off in each shift to take charge of the motor battery, aud it is not necessary to have experienced ex-perienced hands to work the plant. The manager of the mine has stated that the power is sutheient to keep going at least live and probably tsn more stamp-heads, and the whole plant works beautifully. The important lesson taught by this successful suc-cessful application of electric power (which is used for lighting as well as the complete working of the Piurnix) cannot be over-estimated, for there are many gold fields similarly simi-larly situated to the Wakatipu all over Australia. Aus-tralia. These gold fields are often well off for water power, bnt are wanting in the means of transmitting that power to the various va-rious points at which it may be required. With water power the application o? electricity elec-tricity to mining machinery must, before many years have elapscd.'become' very gen-' eral; but even where it is necessary to era ploy steam to generate electric power, in the opinion of many experts, it is a distinct advantage ad-vantage to employ electrical machinery, . , |
