侧向支承压力在深井窄煤柱设计中的应用
pplication of Lateral Abutment Pressure in Deep-well Narrow Coal Pillar Design
煤体侧向支承压力分布在沿空掘巷煤柱宽度设计中具有一定的指导作用。采用钻孔应力计实测研究得出了侧向支承压力峰值距离煤壁10 m,确定煤柱宽度5.0 m。回采期间,沿空煤柱受回采影响范围和程度均有减小趋势。在该矿地质条件下,通过合理的煤柱宽度选择,在煤柱进入采空区时仍会保持部分稳定未破坏区域。
oal lateral abutment pressure distribution in the coal pillar width design has certain directive role. Using borehole stress gauges measured research that the lateral abutment pressure peak distance coal wall was 10 m, thus determine the coal pillar width 5.0 m. Narrow coal pillar by mining influence extent are reduced tendency. Narrow coal pillar will remain stable part without damaging area through a rational choice coal pillar width in the mine geological conditions.
