• TITLE: The Impact of Different Mining and Releasing Ratios on the Over-Support Pressure of Header Working Face

  AUTHORS: Huaji Zhang

  KEYWORDS: Different Extraction and Release Ratios, Overburden Support Pressure, Overburden Destabilization Mechanism

  JOURNAL NAME: World Journal of Engineering and Technology, Vol.11 No.3, August 7, 2023

  ABSTRACT: Through the theoretical analysis of overburden destabilization mechanism, FLAC 3D simplified plane numerical simulation method and field measurement method, we compared the relationship of overburden support pressure at 35 m of workface recovery, and the peak overburden support pressure decreased from 13.85 Mpa to 11.97 Mpa from 1:1 to 1:3. With the increase of mining ratio, the peak over-supporting pressure decreases: with the increase of top coal recovery thickness, the peak over-supporting pressure and the influence range will be further expanded, and the distance between the peak over-supporting pressure and the coal wall of the working face will be further increased and the high stress zone of the peak area will be expanded simultaneously.
