Abstract Underground mining activities will cause strata dislocation changes, especially in the areas where faults are developed and intersected. No hydrological anomaly is found in the first time when the fault is exposed by the roadway. However, after the influence of roadway pressure, it is easy to activate the fault zone. The aquifer water is easy to flow outward through the fault fissures, and it is prone to floor heave and rib spalling, resulting in safety accidents. Taking Xingtai Mine as an example, this paper introduces the effective treatment method of floor heave water caused by fault activation at the intersection of faults in the transportation roadway of 51121 working face, which provides reference for future treatment of similar situations.
