On control of stressed-deformed behaviour of rock mass at roadheading under rockburst hazardous conditions
Abstract. By the 3D finite elements method the problem has been considered for the case of changing stressed-deformed behaviour of rock mass in the near-excavation zone with relief slots forming in the roof differentially remote from the face. The recommendations have been given for control over the rock mass stressed-deformed behaviour in the roof and face of the drift by making relief slots depending on the level of initial stress field in the intact massif.
Keywords: relief slot, stress strain state of rocks, rockburst hazardous conditions
