深部巷道底臌控制研究与锚注支护实践

Deep Roadway Floor Heaves Control Study and Bolt-grouting Support Practice

摘要: 为研究深部巷道底臌控制问题，以某矿-1 000 m岩巷为背景，运用岩土数值模拟软件FLAC^3D，研究了不同支护方案对深埋巷道底臌的控制效果，通过对比提出了全断面锚注的支护方案，并根据现场实测证明了全断面锚注支护可以有效的解决深部巷道底臌问题。

Abstract: In order to study the problem of deep roadway floor heave, based on the background of a mine -1 000 m rock roadway, geotechnical numerical simulation software FLAC^3D is used to study the effect of different support programs to control deep roadway floor heave, the full-face bolt-grouting solution is proposed by comparing different ways. According to the site practice, full-face bolt-grouting solution can control the deep roadway floor heave effectively.
