Comments on the production information

  • TOTAL PRODUCTION FROM 1940-56 WAS 950000 LONG TONS, AT ITS PEAK MINE PRODUCED 380 TIDAY. TIMBERS WERE PULLED AND THE D AS PROPERTY LIES. 1956. BECAUSE OF DEPLETION OF MINEABLE RESERVES SURFACE INSTALLATIONS HAVE IN PART BEEN REMOVED MINE DEVELOPED BY 6 LEVELS. 5600 LEVEL ADIT HAS RAISES TO THE 5750 AND 5900 LEVELS. 5300 LEVEL ADIT(MAIN HAULAGE) IS CONNECTED TO 5100 AND 4900 LEVELS BY A WINZE SUNK ALONG DIP OF PHOSPHATE BED. SHRINKAGE STOPPING WAS TRIED AT FIRST, BUT BROKEN ROCK PACKED AND FAILED TO RUN IN STOPES. LATER OVERHEAD STOPING WAS USED WITH STULL SUPPORTS. DILUTION DURING MINING WAS 15%. H20 AT BOTTOM OF WINZE 120 FT BELOW THE 4900 LEVEL WAS 1350 G/MIN AT TIMES.

Deposit DEPOSIT ALSO IN SECS 4, 6, 10. LOCATED ON NE LIMB OF THE LUKE-GRAVELY SYNCLINE, 6 MILES FROM N.P.RR LOADING PLATFORM AT AVON, AND 2 MILES NE OF LUKE MINE. SAMPLE LOT 1286 FROM USGS PROF PAPER 313-F IS LOCATED HERE. 1 INCH = 100 FEET MINE MAPS (PLAN AND SECTION) ARE ON MICRO- FILM IN SPOKANE. 2 MAPS MINE IS NOW CLOSED (1979). DIPS FLATTEN WITH DEPTH FROM VERTICAL AT THE SURFACE, TO 655 IN THE SE AND LESS THAN 45 SW IN THE NW. A MAJOR NW DIPPING FAULT, WITH AN AVERAGE DISPLACEMENT OF 7 FT, CUTS THE MINE. SE OF THE FAULT THE PHOSPHATE IS SOFT, NW OF THE FAULT IT IS HARD(RECRYSTALLIZED QUARTZ AT THE GRAIN BOUNDARIES OF THE PHOSPHATE OOLITES). RETORT MEMBER AT 3.7 FT THICK IS 35.1% P205
