Full-length anchoring supporting method with intensive resin anchor rod and anchor-shotcrete net

The invention relates to a supporting method by use of resin anchor rod and anchor-shotcrete net for roadway for special growth conditions, such as soft and broken ore rocks, fissuring and cracks. The invention aims to provide a full-length anchoring supporting method with intensive resin anchor rod and anchor-shotcrete net, which can improve the supporting effect, prolong the roadway service time and improve the recovery rate. The supporting method comprises the following steps: A) carrying out loose rock removal after explosion of roadway; B) carrying out primary 50mm simple concrete spraying to the roadway; C) drilling a plurality of rows of main anchor rod hole groups vertical to a roadway rock wall; D) installing the main anchor rods; E) netting by using reinforcing steel bars; F) installing double rib bars on the main anchor rod group; G) endowing prestressing force to the main anchor rod, wherein the prestressing force of each main anchor rod is not less than 78.4kN; H) carrying out secondary 100mm con
