Use of 3DEC to Study Spalling and Deformation associated with Tunnelling at Depth
For mining at depth or deep caving operations, it is increasingly important to better understand the failure process near underground excavations, and for support design, it is necessary to better anticipate the related deformation characteristics of brittle failing rock. This paper describes how 3DEC was used to model the rock mass as an assembly of tetrahedral (tet) blocks bonded at their ...

Impact-Echo Response of Hollow Cylindrical Concrete Structures Surrounded by Soil and Rock: Part II—Experimental Studies
The studies summarized in this paper demonstrate that the impact-echo method can be used for integrity testing of mine shaft and tunnel liners in contact with rock. Results obtained from experimental studies on mine shaft liners are presented. These results show that the measured impact-echo response depends upon the acoustic properties of the surrounding material as well as the acoustic ...

Photogrammetric Joint Mapping for the Relocation of T.H. 53 - Case Study
Project Description The Minnesota Department of Transportation (MnDOT) relocated a portion of T.H. 53 between Eveleth and Virginia, MN. The preferred alignment crosses the existing Rouchleau iron ore pit on a 1,100-foot bridge. Two abutments and one pier of the bridge will be founded on bedrock. Future iron ore mining adjacent to the alignment will create rock slopes up to 500 ft high. After ...

Level and limit level detection with ProGap - Case Study
Application During the process of mining gypsum in a stone quarry, gypsum rock is transported via a series of conveyor belts to the production line. Certain critical conveyors are located remotely from the production line and therefore not visible and suspect to blockages. The customer wants to avoid material overfl ows and blockages between the conveyor belts and a transition chute. Because of ...
