大断面软岩巷道综掘快速施工技术
|
摘要
针对大断面软岩巷道施工无论采用传统炮掘还是普通综掘均存在效率低、安全风险大、施工设备故障多等问题,阐述了一种新施工工艺。文章详细介绍了新施工工艺的工艺流程,施工措施和施工准备,并以内蒙古色连1号煤矿副斜井为实例介绍了施工效果。结果表明:新施工技术经过改进和优化,研究、整合、应用多项创新技术,提高了大断面软岩巷道综掘施工的效率和安全性。
Aiming at the problems such as low efficiency,high safety risk and construction equipment failures in large section soft rock roadway construction using traditional blasting excavation and ordinary comprehensive excavation, a construction technology is introduced. Process flow, construction measures and construction preparation of the new construction technology are introduced in detail,and the construction effect is analyzed based on the practice in auxiliary inclined shaft of Selian No. 1 Coal Mine in Inner Mongolia. The results show that the new construction technology has been improved and optimized,with the application of a number of innovative technologies,the efficiency and safety of the fully mechanized excavation construction for large cross-section soft rock roadway is improved.
