METHOD FOR DETERMINING DEFORMATION OF MINE ROCKS IN ZONES INACCESSIBLE FOR DIRECT MEASUREMENTS

摘要

FIELD: mining.;SUBSTANCE: method involves periodic determination of displacement of reference points located on the slope of mine rocks and earth surface adjacent to it, in vertical and inclined planes and buildup of full vectors of displacement of slope surface. Reference points are arranged in wells drilled in the mine rock massif slope, as per the displacement of which there calculated is a value of relative deformation of mine rocks in the near-slope zone for each well as per a mathematical formula. As per the line attaching the points to critical values of relative deformation there determined is a boundary of potential displacement surface of the near-slope zone rocks.;EFFECT: improving accurate determination of location of potential sliding surface and change of geomechanical state of mine rock massif in vicinity of that surface.;4 dwg
