摘要
基于11101运输顺槽开口段施工断面大、施工条件复杂、传统施工工艺掘进效率低等技术难题,新良友煤矿生产部通过技术研究,对11101运输顺槽开口段采用台阶式分层爆破施工工艺。通过实际应用,降低大断面巷道施工及支护难度,缩短了巷道掘进周期,提高了巷道掘进期间煤矸运输效率,取得了显著应用成效。
Based on the 11101 transportation channel opening section construction section is large,the construction condition is complex,uses the traditional construction craft tunneling efficiency low technical difficulty,the production department of Xinliangyou Coal Mine adopts step-type layered blasting construction technology for the 11101 transportation trench opening section through technical research.Through practical application,it reduces the difficulty of construction and support of large-section roadway,shortens the driving period of roadway,improves the efficiency of coal gangue transportation during roadway excavation,and achieves remarkable application results.
