A mine uses the filling mining method to recover the Step Ⅱ ore pillars and needs to excavate the ore-drawing roadway inside the Step Ⅰ filling body to serve as the bottom ore drawing structure for the pillar recovery,and the direct roof of the ore-drawing roadway is the filling body.To ensure the safety of the roadway formation within the filling body,the study chooses the appropriate roadway excavation means and support method,improves the efficiency of the cohesion of the two,and reduces the cost of roadway excavation and support as much as possible.Referring to similar mine engineering cases,as well as the relevant norms or standards of the country,industry,and typical enterprises,the study proposes 2 schemes,drill-blasting method＋U-shaped steel arch in-advance support and cantilever roadheader＋shotcrete-bolt-mesh joint support.Based on discussion and analysis of the process scheme,the excavation and support efficiency,and the cost,and the technical and economic comparison,it is finally recommended that the mine adopt the joint support scheme of cantilever roadheader＋shotcrete-bolt-mesh to excavate the roadway in the filling body.
