STUDY ON INSTABILITY MECHANISM OF EXTRACTION STRUCTURE UNDER UNDERCUT SPACE BASED ON THIN PLATE THEORY IN BLOCK CAVING METHOD

Study on Instability Mechanism of Extraction Structure under Undercut Space Based on Thin Plate Theory in Block Caving Method

The instability of extraction structure under the undercut space in the block caving stope presents specific characteristics: rib spalling and floor heave in ore-loading roadway and collapse of major apexes.In order to study the stress and displacement evolution law of extraction structure under undercut space and reveal the instability mechanism o

Cell Signaling Coordinates Global PRC2 Recruitment and Developmental Gene Expression in Murine Embryonic Stem Cells

Summary: The recruitment of Polycomb repressive complex 2 (PRC2) to gene promoters is critical for its function in repressing gene expression in murine embryonic stem cells (mESCs).However, previous studies have demonstrated that although the expression of early lineage-specific genes is largely repressed, the genome-wide PRC2 occupancy Ceramic Pla
