Mechanical excavation for tracing circular or elliptical sections with punctual drive machines
The research is aimed at assessing the possibilities for extending the uses of the winning exploitation method which allows better performance during the digging of mines. A tumbler has been adapted for digging circular or elliptical sections. The main achievements were setting up a wagon and transforming the feed table in order to allow the cuttings to be carried out in a curved section, preparing a setting for the handling and laying of supports, the development of a prototype of temporary supports and a system of automatic cut for arched sections.
