Abstract

FIELD: mining industry. SUBSTANCE: invention refers to fastening of workings with roof bolting. Anchor provides for increase of carrying capacity of structure thanks to prestressing of steel rod. Sand and cement mortar includes additive of non-explosive substance HPC-1 and steel rod is fitted with locking elements in locking parts of anchor. Distance between locking elements is less than length of rock hole. EFFECT: increased carrying capacity of structure. 1 cl, 1 dwg

Изобретение относится к горной промышленности, а именно к креплению горных выработок анкерной крепью. Анкер обеспечивает повышение несущей способности конструкции за счет предварительного напряжения стального стержня. Песчано-цементный раствор содержит добавку невзрывчатого разрушающего вещества (HPC-l), а стальной стержень снабжен запирающими элементами в замковых частях анкера, причем расстояние между запирающими элементами меньше длины шпура. 1 ил.The invention relates to the mining industry, and in particular to the fastening of mine workings with anchor support. Anchor provides an increase in the bearing capacity of the structure due to the prestressing of the steel rod. Sand-cement mortar contains an additive of non-explosive destructive substance (HPC-l), and the steel rod is equipped with locking elements in the locking parts of the anchor, and the distance between the locking elements is less than the length of the hole. 1 ill.
