DSI Underground signs an exclusive distribution agreement with NMP of Sweden for dynamic inflatable rock bolts
July 2016, DSI Underground signed an agreement to manufacture and sell patented Dynamic OMEGA-BOLT® with Northern Mining Products (NMP) of Luleå, Sweden. In their quest for higher grade ore, underground mines around the world are going deeper and deeper, where rock mass is often highly stressed by the weight of overlaying strata and by tectonic forces. During the process of developing large excavations, dangerous phenomena such as micro-seismicity and rock-bursts may occur, with violent explosion-like ejection of rock fragments. In order to mitigate the risks of such events, dynamic rock support systems have been developed, and among them, NMP has patented a highly innovative dynamic rock bolt.
