This hollow core bit has hard cutting inserts for drilling into rock. It was used to drill and recover 50mm diameter (most common size) rock cores. The rock cores were assessed by geologists and engineers to provide information for design of structures such as tunnels, dams and underground power stations (eg. McKay Creek Power Station, West Kiewa Power Station). This type of bit was also used where damage to the surrounding rock had to be minimised. The Diamond Drill Bit,used in the early 1900's, when it was primarily used as a method of sampling rock for ore deposits and oil exploration resulting in a "coring" of rock. The use of "coring" to obtained samples for the SEC Kiewa Hydro Electricity Scheme(1920's onward) was to analyse the core to obtain temperature and rainfall patterns shown by the levels of layered solidified soil(rock). This diamond drill would have been used in the early 1900's to provide a sub strata map of temperature and water patterns (over an long period of time). This was a pre requisite to any decisions about the viability of the region to provide the water needed for a successful hydro electricity scheme.This diamond drill for core sampling was at the forefront of the analysis whether to construct a hydro electrical facility in the Kiewa Valley and the adjoining alpine region. The rock core samples produced were assessed by geologists and structural engineers. It was only after extensive core drilling covering the region that solid scientific evidence could be provided to start the "SEC Vic Hydro Electricity Scheme" within its current boundaries.This "diamond" drill bit has eight "teeth" at its cutting edge. The drill creates an 55mm hole in extremely hard rock material to obtain 50mm core samples.. Three quarters down the shank it has thread screw channels to attach the bit to the drill pipe. The coring pipe attaches via screwing it onto this bit. Core samples are the main objective of this tool.alternate energy supplies, alpine feasibility studies temperature, rainfall, sec, kiewa hydro electric scheme, electricity

The core samples in the display cabinet were obtained from the various sites at which drilling into the rock surface was carried out (under the control of design and structural engineers of the SEC Kiewa Hydro Scheme - late 1940's). This function was a precursor to the decision where to locate, in this case, the McKay Creek Power Station. The information gained by structural engineers from the core samples would be used also for the placements of underground tunnels entry and exit points and the overall effective size of the generator plant. This would have included drill and blast techniques (rock characteristics play an import part of explosion control), requirements for support structures and reinforcing cement/steel forms. The use and replenishment of diamond drill bits(the strongest available, see KVHS 0280) was dependent on the "type" of rock found (harder rock required greater numbers of drill bits). Support beams for reinforced ceilings and floors was also a necessity.These rock core samples are very significant in the formulation and placement of the underground Power Stations and their maze of tunnels (in and out) for a successful implementation of the Hydro Scheme. The amount of pre-planning and engineering studies required for such a large scheme must be undertaken to ensure that a "white elephant" was not the result.There are nine columns of rock cores, each 30mm in diameter, set in a wooden display rack. A clear plastic (slide out) protective panel is installed to the front section. Within each column are block details of the depth from which that section was brought from. See KVHS for the appropriate sketch details.Depth levels (retrieved from) are shown for each section on wooden Blocks: 1st Block: "7'10" (seven feet, ten inches), 2nd Block:"9'4" (nine feet, four inches), 3rd Block: "19'3" (nineteen feet, three inches), 4th Block: "24'2" (twenty four feet, two inches), 5th Block: "25'7"( twenty five feet, seven inches) and last block: "30' (thirty feet)"alternate energy supplies, alpine feasibility studies temperature, rainfall, sec, kiewa hydro scheme, electricity

In 1917 Bendigo Amalgamated Goldfield Ltd was formed from the amalgamation of 35 companies with operations on the Garden Gully, Sheepshead, Deborah and Derby lines of reef hoping to increase profits of these existing operations through economies of scale. This was difficult to achieve as the shafts involved were spread throughout the goldfield. Diamond drilling and good geological practices were introduced (Pabst was Chief Geologist) leading to some exploration success. However costs were rising rapidly and in 1923 the directors, deciding that mining would soon become unprofitable, dissolved the company returning assets to the original vendors. J.H. Lenten, Mine Manager, received his second class Mine Manager's certificate in September, 1914 at an examination held at the Bendigo Law Courts. One hundred pages of fortnightly manager's reports for Bendigo Amalgamated Goldfields N.L., Sheepshead Shaft. Reports consist of two pages for each fortnight, signed by J.H. Lenten, Mine Manager.

Central Deborah Gold Mine history: At its peak, Central Deborah Gold Mine reached a depth of 412 metres. It has 17 separate levels and 15 kilometres of drives and cross cuts (tunnels). The Central Deborah was very much a hands-on mine and the conditions that the miners worked in would be considered shocking by today's standards – being lowered underground in a cage with only two sides, often working ankle to knee deep in water, filling up to 32 ore trucks a shift by hand which were then pushed a mile or more along rails in the drives, working by carbide lamp, breathing in the fumes and rock dust and communication by bells. Geez, they were ironmen. However, at the time working conditions were considered to be among the best on the goldfields at Central Deborah, after all it was one of the only mines that had hot showers. Following Central Deborah Gold Mine's closure, the Bendigo skyline began to noticeably change. Obvious remnants of mining such as poppet heads, engine rooms, service quarters, battery houses and chimneys were steadily disappearing. After intense lobbying by the local community, the Bendigo City Council purchased the still very much intact Central Deborah Gold Mine in 1970 for a mere $6,000 to ensure that a vital link to Bendigo's historic golden past was maintained. The Bendigo Trust was then formed to oversee the operations of the Central Deborah Gold Mine, which led to the surface of the mine being opened to the public in 1971. Initially the surface was open for just 12 hours a week and as the demand for viewing a part of Bendigo's history increased, so did the opening hours. In 1974 the mine was gazetted as a Public Historical Purposes Reserve and attracted such visitors as H.R.H Prince Charles. By far the greatest shortcoming at this stage was that no one could view the underground workings, as these had become flooded. After what could only be described as a monumental effort by everyone involved, Level 2 of the mine was officially opened to the public by the Premier of Victoria, the Honourable John Cain, on 20 June 1986, which brought to fruition a long standing dream.Black and white photograph.
