摘要： 随着中国煤矿开采进入深部，巷道围岩变形控制已成为煤矿企业面临的一个突出问题。分析了深部巷道围岩
变形的特点，主要是巷道变形量大、变形时间长且动力灾害显著。为实现对深部巷道的快速有效支护，采用张拉预紧式锚杆。
结合实际情况，探讨了张拉预紧式锚杆在深部巷道围岩变形控制中的应用，可以为深部巷道支护工作提供一定的参考。

Abstract: With China's coal mining into the deep, roadway surrounding rock deformation control has become a prominent
problem faced by coal mining enterprises. The characteristics of deep roadway surrounding rock deformation were analyzed,
mainly including large roadway deformation amount, long deformation time and significant dynamic disaster. In order to realize fast
and effective support of deep roadway, tensioned preloaded bolts were adopted. Combined with the actual situation, the application
of tensioned preloaded bolts in the deformation control of deep roadway surrounding rock was discussed, which can provide some
reference for the support work of deep roadways.

Key words: deep mining; surrounding rock deformation; tensioned preloaded bolt; support
