The invention relates to mining and civil engineering and municipal economy, and can be used at mass investigations of deformed buildings and constructions and rock and earth massifs at destruction of pit and mine fields. By the method of measurement of fissure opening a plot for measurement of fissure opening at object is selected, with determination of its structural position in general hierarchic system of separation of the survey object and the region to which the results of measurements obtained are extended, with setting several parallel lines of measurements across propagation of fissures by the systems of fissures revealed, with account of variability of those, and the scale factor of measurements. According to the invention, locations of accumulation of fissure systems are revealed, with measurement of the angle of propagation of those with direction that determines the basis of orientation of the object, with determination of needed distance to the object of survey, preliminarily rational color, brightness and contrast of raster record corresponding to optimal determination of boundaries of fissure opening are chosen. Information from information template that is installed in the plane of record together with basis is entered to data base. By those data and by the data obtained at recording and processing the screen record positions of opposite boundaries of fissures are determined, and by difference of coordinates of those boundaries opening of fissures is calculated. The method provides increase of quality of measurements, this increases reliability of evaluation of the state of investigation object. |
