Abstract

Изобретение относитс  к горно-добывающей промышленности и м.б. использовано при изучении и контроле геомеханического состо ни  горных пород в окрестност х действующих очистных выработок при камерной системе разработки. Цель - повышение достоверности и информативности результатов при оценке деформировани  кровли по отношению к деформированию целиков. Дл  этого устанавливают репер 7 в кровле камеры и опорные реперы 8, 9 в центре целиков на уровне репера 7. Дополнительно устанавливают репера 10, 11. 12 на уровне почвы соосно с реперами 7 кровли и соедин ют их через измерительные элементы 21, 22,23 жесткими стержн ми 15,16, 18. Репер 7 камеры через измерительный элемент 20 и муфту 19 соедин ют также с опорными реперами 8, 9 жесткими стержн ми 13, 14, 17. При увеличении высоты камеры в процессе отработки стержни 13, 14, 17 наращивают. Величину перемещени  установленных реперов 7-12 определ ют при помощи измерительных элементов 20-23. Сопоставл   результаты измерений деформаций кровли камеры и целиков, производ т оценку деформированного состо ни  системы кровл  камеры - целик. 2 ил. (Л СThe invention relates to the mining industry and m. used in the study and control of the geomechanical state of rocks in the vicinity of existing treatment workings in the chamber system development. The goal is to increase the reliability and informativeness of the results when assessing the deformation of the roof in relation to the deformation of the pillars. To do this, set the frame 7 in the roof of the chamber and the support frames 8, 9 in the center of the pillars at the level of frame 7. Additionally, set the frame 10, 11. 12 at the soil level coaxially with the reference points 7 of the roof and connect them through the measuring elements 21, 22,23 rigid rods 15, 16, 18. The frame 7 of the chamber through the measuring element 20 and the coupling 19 is also connected to the support frames 8, 9 by rigid rods 13, 14, 17. As the height of the chamber increases, the rods 13, 14, 17 are increasing. The amount of movement of the established frames 7–12 is determined using measuring elements 20–23. Comparing the results of measurements of the deformations of the roof of the chamber and the pillars, an estimate is made of the deformed state of the roof system of the chamber — the rear sight. 2 Il.
