Progress in the development of mechanized stoping methods

Progress during the last two years in the Chamber of Mines programme for the development of mechanized stoping methods is reviewed, and advances in the basic technology are outlined. Specifically. advances in the understanding of rock fracture around stope faces. in rockbreaking techniques, in rockhandling techniques, and in engineering are described. The state of development reached with mining systems based on cutting, impacting. and blasting is also described.
