摘　　要：针对塔山煤矿三盘区2305顺槽掘进交叉2#层三盘区皮带巷期间,受两巷间距影响,出现巷道顶板锚杆(索)支护难度大、支护效果差等技术难题,在交叉段采取分层爆破施工工艺,并采取“穿层锚索+工字钢棚”联合支护技术。应用效果表明,改进的掘进工艺保证了近距离立体交叉巷道掘进效率及施工安全。To solve the technical problems of roadway roof bolt(cable)support difficulty and poor supporting effect in driving the overpassing belt roadway in Tashan Colliery,the layered blasting construction technology and the combined support technology of"through-layer anchor cable with I-typed steel shed"are adopted in the intersection,whose application effect shows that the improved excavation technology ensures the close-distance excavation efficiency and construction safety of over-passing roadway.

关 键 词：掘进巷道 分层掘进 联合支护技术
