METHOD OF INSTALLATION OF ANCHORS FOR ROCKS Russian patent published in 2009 - IPC E21D20/02 

FIELD: mining.

SUBSTANCE: invention refers to mining, namely to method of anchors installation. Drill-rod with inner passage is put into rock. Through inner passage fluid self-consolidating mass is charged and thus ready borehole is filled with mass, so that mass consolidates in borehole with drill-rod remaining in borehole. Consolidating mass is a combination of consolidating plastics and plastics inducing consolidation. Mentioned plastics are supplied to inner passage of drill-rod during predetermined time of supply F which corresponds to time of consolidation H. Time of consolidation is predetermined by means of choice of plastics and ratio of their combination in such a way that time of supply actually corresponds to time of consolidation and actually results in complete filling of working area by consolidating combination between point of mixture and borehole outlet.

EFFECT: providing of automatic filling of borehole by consolidating mass along its whole length, reduction of time required for mass consolidation, improving of safety of mining operations.
