Development Orientation and Status of Floor Heave for Gob-side Entry Retaining in China

Aimed at the significant function of prevention and control of floor heave on the surrounding rock control of gob-side entry retaining, we make a conclusion and analysis on research situation of the domestic characteristics of floor heave of gob-side entry retaining, mechanism of floor heave, influencing factors and prevention and control technology by the systemic review of literature, and also make a predication of the research direction. We point out that the gob-side entry retaining with large section of deep mine is the tendency of development. Therefore, we should make a deeper research on the basic theory related to mechanism of floor heave, actively explore and research the mechanism of floor heave about different rock bottom, and construct the appropriate and effective control technology of floor heave in gob-side entry retaining.
