METHOD FOR SUPPORT OF MINE WORKING FLOOR ROCKS TENDING TO HEAVING

摘要

A method for support of mine working floor rocks tending to heaving includes drilling of blast holes by the floor, placement of fiberglass plastic reinforced tubular anchors with longitudinal action there, with fixation of those to massif with a circular layer of synthetic tires, and under conditions of stable rocks of the adjacent strata formed with sandstone that make possible earth rising up to fiberglass anchors are installed in one line with fixation of the working with chemical consolidation with the walls of the blast hole by whole length of the anchor with strength not less than 1.1 kN per running centimeter, and density of those is not less than one anchor per square meter. The installation of anchors is carried out prior to development of non-elastic deformations at the outline of the working.
