Abstract:
Mine Shaft Locations were collected by a variety of methods from 1869 in some areas of the state. Mainly concentrating in Ballarat and Bendigo. In places a shaft may be recorded multiple times with a different source. In cases where several shaft locations are shown close together (generally with separations less than stated position errors) and they have different sources, it is possible that one shaft has been mapped several times. In cases where several shaft locations are shown close together but they have the same information source, it is possible that each shaft location represents a different shaft on the ground.

The Mines Department was the forerunner to Minerals and Petroleum Victoria. The Mines
Department carried out an extensive shaft filling and capping operation between the 1930s and
1950s. More than 1600 shafts were either filled with mine mullock (waste rock from the mining
process) or capped with a reinforced concrete cap. The decision to either fill or cap was
usually based on the depth of the shaft. The shaft was filled if less than about 50 m deep otherwise it was usually capped. Much of this work was carried out under the supervision of Frank Vincent, a mines inspector. During the reclamation programme he arranged for the location of each shaft to be mapped by the tape and compass method. The size of the shaft at the surface (the shaft collar) was measured and an estimate of the shaft depth was obtained.
These details together with the reclamation method (filled or capped) were recorded in a list of 1600 shafts. Where possible, this data has been included in the attribute data in the Bendigo Shaft Hazard database. Frank Vincent's original shaft reference number is recorded as the VINCENTNO in the shaft attribute data. The size of the shaft collar is recorded as COLLARFT.
The shaft depth as estimated by Frank Vincent team, is recorded as the DEPTHM. In the case of shaft depth we have converted the original estimate in feet to metres. The information from Frank Vincent's data shows that most shafts have depths in the range 10 to 20 metres although
a considerable number have depths in the range 100 to 200 metres.

Data Source:
Came from mineshafts digitized for use with GINGER around 1990. Plus a special project undertaken by Bendigo to record the locations in 2000.
Sources are as follows.
Source 1
1:2500 plans (DNRE 1980s)
No of shafts: 1248
Shafts plotted on a set of modern cadastral plans at scale 1:2500. Most of these shafts were mapped by Departmental officers through the 1970s to 1999. The mapping method used was mostly tape and compass survey.
Source 2
1:5000 Plots (Frank Adams c1970s)
No of shafts:1237
Frank Adams was a draftsman in the Mines Department during the 1970s. He hand plotted the positions of shafts on to a set of 1:5000 maps based on surveys carried out between the 1870s and 1950s. The survey information is recorded in a set of field books held in Minerals and Petroleum Victoria archives. Some of the early surveys were by theodolite and chain but most of the later surveys (1930s and later) were by the tape and compass method. Many of the surveys for the period 1930s to 1950s were mapped as part of the Departmental shaft reclamation programme (see section 4).
Source 3
Bendigo City Council
No of shafts:81
Shafts located by the Bendigo City Council and plotted onto the 1:2500 cadastral plans (Source 1).
Source 4
Bendigo Mining NL (2000)
No of shafts:15
Shafts surveyed by Bendigo Mining NL usually by modern theodolite technology.
Source 5
Lease Ozalids (Landry c1990)
No of Shafts: 1478
Shafts transferred to Source 1 from a set of small and unbound cadastral plans showing lease boundaries (for the period 1930s to 1950s). The information for the shaft locations probably derived from the same field books used to locate shafts by Frank Adams (Source 2).
Source 6
Lease surveys (c1870s)
No of Shafts: 1206
During the late 1860s and early 1870s an application for a new lease was usually accompanied by an accurately surveyed plan showing lease boundaries, shaft locations, water courses, buildings and gardens. The shaft locations were transferred to the 1:2500 cadastral plans (Source 1) from original lease survey registers.
Source 7
Swiney (1994)
No of Shafts: 3
Shaft locations computed by Don Swiney in 1994. The information was derived from old field books.
Source 8
Western Mining Corporation Ltd (1980s) 20
No of Shafts: 20
Shaft locations surveyed by Western Mining Corporation Limited in the 1980s using modern surveying techniques.
Source 9
Lease Ozalids (Swiney 1994) 1043
No of Shafts: 1043
Shaft locations transferred from a set of small and unbound cadastral plans showing lease boundaries (for the period 1930s to 1950s) onto second set of 1:2500 cadastral (different to Source 1). The information for the shaft locations probably derived from the same field books used to locate shafts by Frank Adams (Source 2).
Source 10
Digitised for Ginger
No of shafts: 5368
Shaft locations compiled for the three published 1:10,000 maps (Willman & Wilkinson, 1992). Sources of information included Sources 1,2, 5,6 & 8. Many other shafts were located using old newspaper and company records. The accuracy of these shaft locations, particularly those derived from newspaper and company records, is generally poor. However this database includes many shafts not located in any of the other sources.
Note: In 2015 Bendigo City Council added data for shafts that appeared in the floods of 2011.
