often in 4D space, of such phenomena as change of stresses (deformations) in rocks, cracks (rock burst), vibrations, faults, displacements, settlements, uplifts, cavities, changes in ground temperature generated e.g. by infiltration of fluids, and even fluid flow with identification of its velocity. The paper will present the contemporary possibilities of various DFOS fibre optic techniques that can be used in mining for global and local assessment of the workings of the rock mass and the mine excavations located in it. KEYWORDS: DFOS, fibre optic sensors, DSS, DTS, DAS, microseismics
