摘 要:随着我国经济水平的不断提高,矿建工程巷道研究受到广泛的重视。在矿建工程巷道掘进过程中,锚杆支护至关重要,人们必须确保支护施工具有极强的稳定性,同时具有较高的机械化水平。与传统的支护技术相比,锚杆支护能够有效缩短施工周期,降低施工成本,因此对矿建工程巷道掘进锚杆支护的研究越来越多。但是,在矿建工程巷道掘进过程中,实际工况是不稳定的,因此在实际支护施工中仍有许多问题尚未解决。人们应当采取措施对施工进行改良、控制,进而提高锚杆支护的整体质量。

Absrtact:With the continuous improvement of China's economic level, the research of mine construction engineering roadway has received extensive attention. In the process of tunneling in mine construction engineering, bolt support is very important, people must ensure that the support construction is extremely stable and has a high level of mechanization. Compared with traditional support technology, bolt support can effectively shorten the construction cycle and reduce construction costs, therefore, more and more researches have been made on bolt support for mine roadway excavation. However, during the tunneling process of the mine construction project, the actual working conditions are unstable, so there are still many problems that have not been solved in the actual support construction. People should take measures to improve and control the construction, so as to improve the overall quality of bolt support.

在矿建工程的建设过程中,施工单位通常高度重视巷道掘进,积极提高巷道掘进施工质量,以确保后续开采安全、顺利进行,减少事故发生率。当前,矿建工程巷道掘进施工要合理应用锚杆支护技术,锚杆支护是一种新型支护方式,能够在矿建工程巷道掘进施工中发挥重要的作用,有效加固巷道,提高巷道稳定性和开采效率,保障开采安全。

1 锚杆支护技术的特点

矿建工程巷道掘进施工过程中,施工单位必须加强先进巷道支护技术的应用,以提高巷道整体的安全性与稳定性。传统的矿建工程巷道掘进大多采用棚室支护,需要投入大量的人力、物力、財力,极大地提高了实际施工所需的各项成本。随着市场经济的进一步发展,这样的支护技术已经无法满足目前支护工作的需要,锚杆支护技术逐渐走入人们的视野,并且已经得到了广泛的运用。……
