| Footage description: | Film shots of tin miners drilling ore at the face. Ian Boustead introduces the programme. Aerial shots of the Wheal Jane mine in Cornwall and shots of a model of the mine. John Stocks (Imperial College) gives a brief history of tin mining at the Wheal Jane site. He lists the major drawback facing the early miners (lack of knowledge of the sub-surface geogogy of the ore body) and how this is over come today by sub-surface surveys using the diamond drilling technique. Stocks examines a diamond drill and three cores from the Wheal Jane area. He explains that a result of these surveys, Consolidated Goldfields decided to re-open the Wheal Jane mine a new mine. Pointing to a sub-surface geological model of the Wheal Jane area Stocks explains the various methods by which access to the ore body can be obtained by the miners. He lists the advantages and disadvantages of each and gives the reason for Consolidated's choice of shaft. Film shots of the old Wheal Jane shaft being reopened. John Stocks, pointing to the mine model, goes on to explain how access to the ore body is obtained once a vertical shaft has be sunk. He points out the system of drives and crosscuts which result. up to surface. Using the sub-surface geological model of the mine, Stocks goes on to explain how the ore is extracted. He also uses another model and a film clip of miners drilling and blasting to help illustrate his points. Stocks then goes on to explain how the ore is moved underground in preparation for its removal to the surface. Shots of an underground locomotive and cars containing ore. Stocks explains the need for ventilation shafts in a deep underground mine such as Wheal Jane, He then goes on to explain, with the aid of a model, how the ore is moved to the surface. Shots of ore being moved on conveyor beIts. Ian Boustead sums up the programme. |
