Experimental study on mechanical mining with cantilever roadheader in a gold mine.

As the key equipment in modern tunnel construction and underground engineering, the technology of cantilever roadheader is also constantly innovating to adapt to more complex and diversified geological conditions. However, due to the uncertainty of geological environment and the limitations of the equipment itself, the cantilever roadheader still faces many challenges in practical application. Based on the actual situation of the mine, the mechanical mining test study of cantilever roadheader was carried out. Firstly, the research on the cuttability of rock mass was carried out, and it was found that the cuttability of the mine from shallow to deep orebody showed a trend of changing from difficult to easy. Based on the rock breaking capacity, equipment pure cutting capacity, mine actual production capacity and equipment cost performance, the equipment selection of cantilever TBM was carried out. Finally, the field industrial test shows that the mechanical driving roadway has the good forming effect and little influence on surrounding rock. The relevant research results can provide useful reference for the practical application of the cantilever roadheader under similar ore body conditions, and promote the technical progress in the field of mechanical mining.
