METHOD FOR DETERMINATION OF SHIFTS AND DEFORMATIONS OF SURFACE OF EARTH AT COMPLICATED CONTOUR OF BREAKAGE HEADING

摘要

Method for determination of shifts and deformations of surface of Earth at complicated contour of breakage heading includes measurement of lengths of face and extraction stem of breakage heading in mine, measurement on surface for determination of positions of actual calculated points for plotting real contour of breakage heading and application of real calculated points at layout of mine workings, smoothing of contour of breakage heading with sides parallel to guides of propagation and fall of rocks, choice of direction of a coordinate system. According to the method, one determines calculated points that are placed from smoothed contour of breakage heading at distance same to that for respective calculated points from real contour of face.
