Abstract

FIELD: mining, method is used in sphere of underground workings supports timbering, for anchor supports fixation in boreholes (blast holes) using chemically hardened compositions. SUBSTANCE: aim is to decrease time period of anchor mounting, maximum decrease operations of boreholes drilling, prevention of hardening solution losses. Boreholes air is removed by filling the boreholes with hardening solution through injector in volume, that is equal to difference of boreholes volume and anchor volume, that is introduced in boreholes. EFFECT: decreased anchor mounting time period, maximum decreased volume of boreholes drilling operations and losses of hardening solution.

Задачами изобретения являются сокращение времени установки анкера, максимальное уменьшение объема работ по бурению скважин и ликвидацию потерь закрепляющего раствора. Поставленные задачи решаются тем, что из скважины удаляют воздух путем заполнения ее закрепляющим раствором через инъектор в объеме, равном разности объема скважины и объема анкера, вводимого в скважину.The objectives of the invention are to reduce the installation time of the anchor, the maximum reduction in the amount of work on drilling wells and eliminating the loss of fixing solution. The tasks are solved in that air is removed from the well by filling it with a fixing solution through the injector in a volume equal to the difference between the volume of the well and the volume of the anchor introduced into the well.
