Many mines in Canada have adopted sublevel stoping method or one of its variations, such as blasthole stoping (BHS) and sublevel longhole retreat (SLR), for the extraction of steeply dipping orebodies. Stope, as the basic excavated element, plays a significant role in the whole process of mining activity. In the mining method of BHS, crossing cuts are excavated at tops and bottoms in each stope for drilling blast holes and transportation of mined out orebodies. Crossing cuts failure may result in prolonged production interruption, fatality, and equipment loss. After the completion of orebodies excavation from the sublevel open stope, the …
