针对采用传统的钻爆法或冻结法结合有轨车辆或无轨车辆出渣施工方式进行长距离斜井开拓存在设备多、调度和运输管理要求高、出渣效率低等问题,分析了盾构掘进结合连续输送机出渣施工方式的优势,介绍了该施工方式中连续输送机的结构,指出了连续输送机急需改进的关键技术,包括大容量储带技术、智能化输送带张紧技术、快速收放带技术、安全延伸安装技术、控制保护技术.补连塔煤矿的实际应用表明,盾构掘进结合连续输送机出渣施工方式的掘进速度是传统施工方式的4～5倍,能够满足煤矿长距离斜井快速施工的要求.%In view of problems of traditional construction method for long-distance inclined shafts development which uses drilling and blasting method or freezing method combined with rail or trackless vehicles for slag-out,that it needs many equipments,has high requirement for scheduling and transportation management and low slag-out efficiency,superiority of the construction method using tunnel boring machine for excavation with continuous conveyor for slag out was analyzed.Structure of continuous conveyor was introduced.The key technologies need to improve were pointed out,including large capacity belt storage technology,intelligent conveyor belt tensioning technology,fast belt take-up or retracting technology,safe extension installation technology,control and protection technology,etc.The practical application of Bulianta Coal Mine shows that excavation speed of the construction method using tunnel boring machine for excavation with continuous conveyor for slag-out is 4-5 times of that of traditional construction mode,which can meet the requirements of rapid construction of long distance inclined coal mine.
