Abstract
Изобретение относитс к области горного дела и может быть использовано при возведении монолитной крепи горных выработок. Целью данного изобретени вл етс повышение надежности и опалубки путем увеличени жесткости в направлении и снижение уровн фронта ударной волны при взрывной отбойке. Секци опалубки включает внутреннюю обечайку, котора со держит среднюю и боковые вертикальные части, кажда из которых по высоте состоит из трех жестко св занных между собой элементов . Центральный элемент 13 средней вертикальной части выполнен с цилиндрической поверхностью, котора равноудалена от наружной обечайки. Центральные элементы 14, 15 боковых частей жестко св заны с наружной обечайкой и имеют цилиндрическую поверхность с радиусом кривизны, отличным от радиуса кривизны центрального элемента 13 средней части, а крайние элементы 16, 17, 18 средней и боковых частей выполнены с конусными поверхност ми и жестко св заны с наружной обечайкой, причем крайние элементы 16, 17 боковых частей выполнены с одинаковым радиусом кривизны, отличным от радиуса кривизны крайних элементов 18 средней части.4 ил. (Л СThe invention relates to the field of mining and can be used in the construction of monolithic lining of mine workings. The purpose of this invention is to increase reliability and formwork by increasing the rigidity in the direction and reducing the level of the shock wave front during blasting. The formwork section includes an inner shell, which contains middle and lateral vertical parts, each of which in height consists of three rigidly interconnected elements. The central element 13 of the middle vertical part is made with a cylindrical surface that is equidistant from the outer shell. The central elements 14, 15 of the side parts are rigidly connected to the outer shell and have a cylindrical surface with a radius of curvature different from the radius of curvature of the central element 13 of the middle part, and the extreme elements 16, 17, 18 of the middle and side parts are made with conical surfaces and rigidly associated with the outer shell, and the extreme elements 16, 17 of the side parts are made with the same radius of curvature, which is different from the radius of curvature of the extreme elements 18 of the middle part. 4 Il.
