Supporting Progress: The Role of Immediate Forward Support Machines in Tunnel Construction (1960s)
The film discusses the development of immediate forward support systems for mining machinery in Great Britain, particularly focusing on the use of ranging drum shearers in thick seams. It highlights the effectiveness of 200-ton forward support systems, which ensure roof control and prevent falls during cutting operations. The film details the hydraulic mechanisms and control systems that enhance cutting speed and safety, showcasing successful implementations in various mining locations despite challenging roof conditions.
