FIELD: mining.SUBSTANCE: method involves measurement of stresses in mine rock body beyond the limits of an influence zone of second (mining) working at different depth when using underground mine workings, build-up of charts (dependences) of variation of the obtained primary stresses with depth. In order to improve forecast accuracy of stresses, including at horizon depth, each of the primary stresses is divided into constant and variable (pulsating) components in time. Relationship between variation of constant component parts with depth is obtained; a law of variation of variable (pulsating) stresses in time is found; then, these component parts are added at the required depth and the required time.EFFECT: improving forecast accuracy of stresses on lower horizons in the future and at use of measurement results in the past on upper horizons.2 dwg, 1 tbl |
