MINING. FIRST PAPer. Mr. F. M. Krausé, F. G.S., F.L.S. GEOTECTONIC AND CHEMICAL. 1. Prepare a section extending 3,000 feet laterally and 2,000 feet in depth, illustrating the undermentioned features: - Fundamental granite, granite apophysis, felsite dyke, diorite intrusion, lava flow, basalt neck, slate and sandstone dipping W. 75°, deep lead, terrace drift, alluvium, fissure vein dipping E. 80°, quartz segregation, strike fault hading W. 50°. The section to be transverse to strata and veins, and accurately drawn to a uniform scale of 300 feet to the inch. 2. The gossan of a lode contains quartz sinter, limonite, scorodite, chrysocolla, cervantite, bismite, smithsonite, anglesite, native gold, and native silver. State what minerals you would expect to find in the lode below the water level, giving specific reasons for so concluding. 3. In one portion of a tin-field the ore is wholly won from lodes, the alluvial being practically barren. Another part of the field affords extensive supplies of stream tin, while the veins are unproductive. To what cause or causes may these differences be attributed? 4. Explain the mode of occurrence and probable origin of the masses of secondary gold found associated with the "indicator" veins at Ballarat East. 5. Mention the principal constituents of the gangue and ore of mineral veins; state which of these constituents are known to be present in sea water, thermal springs, the micas, amphiboles, and pyroxenes respectively; and point out what bearing this information has on the theory of lateral secretion. 6. A mining property containing ten acres, of square shape, and with boundaries bearing to the cardinal points, is traversed by an auriferous quartz vein dippingE. 14° N. 80°. The lode crops out at the centre of the north boundary of the block and pitches S. 22°. Its width is two inches at the cap, and increases gradually to three feet at a depth of 1,000 feet. You are asked to appraise the mining value of an adjoining square ten-acre block, the north boundary of which coincides with the south boundary of the first-mentioned property. Assuming the surface of the ground to be level, and the dimensions of the lode persistent throughout, determine (a) How many feet of backs there are at the northeast corner of the southern block. (b) How many tons of veinstone the southern block will yield. In addition to the calculation paper furnish a plan drawn to a scale of 200 feet to the inch. MINING. SECOND PAper. Mr. F. M. Krausé, F.G.S., F.L.S. MINING ENGINEERING. 1. Give full particulars of the operations of boring and blasting, including details of the hand and machine drills. 2. The influx of water in an alluvial mine is at the rate of two million gallons per 24 hours. The sump is 480 feet below brace of shaft. State (a) Required horsepower. (b) Size of plunger pumps, with a 9-feet stroke, and working five strokes per minute. (c) What allowance you would make for friction, leakage, and other contingencies. (d) Prepare a sketch of a lift between two plunger chambers, shewing manner of securing plunger frame and pumps. 3. Describe the method of constructing a spherical timber dam across a gallery 8 feet high and 5 feet wide, situated 600 feet below the level of permanent saturation. Illustrate by longitudinal and transverse sections. 4. A mine has a single shaft 1,000 feet deep, at which level a cross-cut has been driven 500 feet long. At the face of the latter a rise has been put up 100 feet high. State how you would ventilate this rise in the absence of an ordinary ventilating machine. 5. Under the Regulations of Mines and Mining Machinery Act it is necessary to provide "a proper ladder or footway." Prepare a sketch of 60 feet of such footway, the compartment being 5 ft. x 3 ft. in the clear. Shew position of landings, size and form of man holes, details of ladders with iron sides and rungs, position of ladder in regard to sides of shaft, stays, fastenings, &c. 6. An overhand stope, 200 feet long, is approaching old workings where the lode was 40 feet wide, and filled with deads. Explain how you would secure the ground and remove the final 10 feet of veinstone. |
