Abstract The point-surface comprehensive measurement method to check the grouting effect in mined-up region under highway is presented. Through comprehensive measurement test，it indicates that the prospective grouting effects are verified. Besides the general and direct methods such as bole sampling and injection test，etc.，three-lateral resistivity logging and high-density resistivity methods are effective to check the grouting effect in saturated mined-out region. Even if the point-surface comprehensive measurement methods are adopted，the grouting effect can be evaluated accurately and fully.
