锚索支护技术在我国煤矿应用发展较快,其特点是锚索可锚入到深部较稳定的岩层中并可施加预应力。详细介绍了MH型煤矿巷道锚索系列的结构形式和工艺特点。通过所列举的工程应用实例,说明了这种巷道锚索在大硐室支护、破损巷道及不良地层加固方面所起的重要作用和显著效益。
The application of the anchor cable support technology in our country is developing rapidly. Its characteristic is that the anchor cable can be anchored into the more stable deep strata and can be prestressed. The structure type and technological characteristics of the anchor coal mine tunnel series MH are introduced in detail. Through the examples of engineering applications listed, this paper illustrates the important role and significant benefits of this kind of roadway anchor cable in supporting large caverns, damaged tunnels and reinforcement of poor strata.
