佛洼15号煤采区15124走向高抽巷掘进作业分析

Excavation of 15124 High Drainage Roadway in No.15 Coal Mining Area in Fuwa

巷道掘进的作业方式对于施工安全和效率有显著的影响。结合佛洼15号煤采区的实际情况,对高抽巷掘进作业中的巷道支护和掘进工艺进行分析。在巷道支护设计中,重点分析了支护参数的选取和支护的施工工艺;在掘进工艺中,重点分析了掘进作业方式和爆破作业方式,以期为巷道的快速掘进提供一定的参考。

The operation mode of roadway excavation has a significant impact on construction safety and efficiency.Combined with the actual situation of No.15 coal mining area in Fuwa,this paper analyzed the roadway support and tunneling technology in the tunneling operation of high extraction roadway.In the design of roadway support,it focused on the selection of support parameters and the construction technology of support;it focused on the analysis of the tunneling operation mode and blasting operation mode in the tunneling technology,in order to provide a certain reference for the rapid tunneling of the roadway.
