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

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.
