    Abstract At the end of the openpit mining process in large metal mines, the mining model must change from openpit mining to underground mining, but the mutual interference between the two mining models leads to poor production safety conditions and difficulties in production convergence during the transition periodThe openings made in the process of extracting ore are called stopes or rooms There are two steps involved in stoping The first is development—that is, preparing the ore blocks for mining—and the second is production, or stoping,mining Underground mining | Britannica
