Research and Application of Support Technology for Track Roadway in Deep Buried Mining Area of Coal Mine
The application of large-section roadway support technology in coal mines was deeply discussed,the influence of geological structure,coal seam structure and roadway location on the support scheme was analyzed,and the importance of factors such as roadway size,shape design,ground pressure and rock burst pressure on the selection of support scheme was made clear through the study of specific cases.In practical application,for the conglomerate layer and rock burst danger area in the study area,the combination support of high-prestressed strong anchor bolt and cable was adopted,supplemented by the combined support of shotcrete.Moreover,through geological exploration and adjustment of roadway size,the supporting structure can better adapt to the complex changes of coal seam and strata.The results showed that the support scheme can effectively improve the stability and safety of the roadway.
