File contains images depicting the underground mine at Cassiar, showing structural damages, repaired damage ground support, and mining and repair processes.

The file contains a photo inventory entitled “Underground Mine Structural Inspection, Rock Mechanics Dept. Foto Documentation” with a complete file inventory linking the picture number to a location, title, and dated film. This photographic documentation was assembled for the purposes of liaising with a underground mining consultant located in South Africa.

• Images document structural ground support including steel cables, support arches, metal mesh, shotcrete, rockbolts, wooden beams.
• Images show ground support damaged through ground movement, but some depict newly installed or repaired support.
• Images depict ventilation ducting that was crushed or torn.
• Mining processes depicted include miners installing a rock breaker, miners paving the adit floor with concrete, miners inspecting a damaged section of mine, miner loading drill or blastholes with ANFO (ammonium nitrate / fuel oil mixture) explosives, and long hole drilling.
• Technical elements of the underground mine depicted include a mining device and ore in a chute (annotated ‘1290 crusher’), the conveyor, ‘LH drill’, ore processing machine annotated ‘1350 breaker’, and an electrical box titled ‘Weighometer’.
• Specific locations shown include ore draw points, ore passes, access drifts, a hatch and door titled “Fuel station 1415”, and a dead end drift with a stack of equipment and an orange cable annotated “1335 access electrical stations”.

This file contains various aspects of the underground mine.

• Photos depicting damage to the underground mine such as fallen rocks, cracked shotcrete, twisted rock bolts and metal mesh, exposed and damaged steel structural frames, and repairs underway.
• Steel cables, chains, support arches, and custom welded rebar frames used in the structural reinforcement of the underground mine.
• Several engineering tests related to the structural damages are depicted.
• Two sets of images show a Porta Power hydraulic tool with a ready rod attached, a hand pump, as well as images of a technician testing the holding power of a rock bolt.

File contains photographs featuring the tramline at Cassiar which ran from the crushing plant at the mountain mine to the plantsite in the valley (a drop of 427 meters). The first ore was originally transported by truck to the plant until the gravity chute was built in 1953. This chute was replaced with the first aerial tramline model in 1956, which was succeeded by the second model in 1975. This file also includes one photo of the original gravity chute, and one photo depicting a tramline worker.

Additionally there is a collection of eighteen photographs of tramline cars that were being surveyed for damage and condition, and another collection of six photographs of tramline study. The results of this study determined that there was variances in load sizes of the buckets caused by extra material falling off the panfeeder.

These 9 images are associated with materials dated Nov. – Dec. 1976 and it is likely that these photographs were taken in the winter of 1975-1976.
