Fair 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. 

Positional Accuracy

Comments

Approximately +- 100 metres Same sites could be recorded multiple times - different sources in the Bendigo area Digitized for Ginger has worse accuracy than other sources.
