Determination of the Deformation Behaviour of Salt Rock by Evaluation of Convergence Measurements in Shafts
Available to Purchase
Paper presented at the ISRM SINOROCK 2013, June 18–20, 2013
Paper Number: ISRM-SINOROCK-2013-140
... Abstract Convergence measurements are an essential part of monitoring methods in underground openings. They also provide important information about the mechanical behaviour of the rock mass in the framework of site exploration. In shafts a more accurate estimation of the deformation behaviour...
