摘　　要：深入探讨了大断面巷道支护技术在煤矿中的应用,分析了掘进区域的地质构造、煤层结构及巷道位置对支护方案的影响,并通过研究具体案例,明确了巷道尺寸、形状设计、地压和冲击地压等因素对选择支护方案的重要性。在实际应用中,针对研究区域的砾岩层和冲击地压危险区域,采用了高预应力强力锚杆锚索组合支护方式,并辅以喷射混凝土的联合支护方式,而且通过地质勘探和调整巷道尺寸,使得支护结构可以更好地适应煤层和地层的复杂变化,结果表明,该支护方案可以有效提高巷道的稳定性和安全性。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.
