Surface mining-induced fissures formed in shallow coal seam mining have serious impact on safety mining and water resources protection.
This paper proposes a novel approach to study the formation mechanism and dynamic development of surface mining-induced fissures in shallow coal seam mining.
This approach combines field tests, theoretical analysis, and numerical simulations based on the geological condition of shallow coal seam mining in Chuancao Gedan Coal Mine.
Two typical surface mining-induced fissures, step-type fissures and collapse-type fissures, are generated in shallow coal seam mining.
The fissures with large vertical throw or horizontal opening severely impact water resource protection and surface ecological environment.
Surface mining-induced fissures are generated periodically and changed dynamically with the advancing of working face.
The vertical throw and horizontal opening of surface fissures are changed dynamically with the movement of loading key strata.
The movement forms of loading key strata determine the morphological development of surface fissures.
Downward sliding movement of broken rocks causes step-type fissures, while downward rotation movement leads to collapse-type fissures.
The degree of the downward sliding and rotation of broken rocks determines the vertical throw and horizontal opening of surface fissures.
This paper proposes mining technologies to reduce damaging ground fissures in shallow coal seam mining and analyzes their control effects.
