Abstract

Способ определения вертикальных сдвижений и деформаций, включающий закладку основных профильных линий, располагаемых по простиранию и вкрест простирания пласта угля или рудной залежи, и дополнительных профильных линий, располагаемых в других направлениях в пределах границ мульды сдвижения, зафиксированных через равные интервалы рабочими и опорными реперами, располагаемыми на концах профильных линий вне зоны сдвижения, систематические определения высотного положения рабочих реперов относительно опорных до начала и в период сдвижений земной поверхности, получение оседаний, вычисление наклонов и кривизны соответственно как первая и вторая производная от оседаний, отличающийся тем, что до начала сдвижений поверхности производят закладку не менее четырех опорных реперов вне зоны сдвижения, два из которых располагают на линии максимальных оседаний по простиранию пласта или рудной залежи и два других - перпендикулярно линии первых двух, то есть вкрест простирания пласта или рудной залежи, производят лазерно-сканируюшую съемку потенциальной зоны подработки до начала сдвижений и повторные съемки того же участка после начала сдвижений, устанавливая при каждой съемке марки внешнего ориентирования на опорные реперы, по результатам съемочной работы лазерно-сканирующей системы строят трехмерные точечные модели участка подработки земной поверхности, используя которые, получают оседания, как разность соответствующих профилей точечной модели, отражающей состояние поверхности участка до начала сдвижений и профилей модели, отражающей состояние того же участка на определенную стадию процесса сдвижения, вк A method for determining vertical displacements and deformations, including laying the main profile lines located along the strike and across the strike of a coal seam or ore deposit, and additional profile lines located in other directions within the boundaries of the displacement mold fixed at regular intervals by working and supporting reference points located at the ends of profile lines outside the zone of displacement, systematic determination of the altitude of working benchmarks relative to the reference ones before and during shifted earth surface, obtaining subsidence, calculating the slopes and curvature, respectively, as the first and second derivatives of subsidence, characterized in that before the start of surface displacements, at least four reference frames outside the displacement zone are laid, two of which are located on the line of maximum subsidence along the strike of the formation or ore deposit and the other two - perpendicular to the lines of the first two, that is, across the strike of the formation or ore deposit, laser-scanning the potential zone of the side job is performed before of movements and repeated surveys of the same area after the start of the movements, setting the marks of external orientation on the reference frames at each survey, using the results of the shooting of the laser-scanning system, three-dimensional point models of the part of the undermining of the earth's surface are constructed, using which they get subsidence, as the difference of the corresponding point profiles a model that reflects the state of the surface of the site before the start of displacements and profiles of a model that reflects the state of the same site at a certain stage of the displacement process, including
