运用理论分析与数值模拟对沿空掘巷合理窄煤柱宽度进行研究,通过分析不同宽度煤柱下巷道垂直应力和水平位移的分布,以及巷道顶底板和两帮相对移近量,确定了合理的窄煤柱宽度。现场应用效果表明,研究确定的窄煤柱宽度合理,为沿空掘巷窄煤柱宽度的确定提供了依据。 By using theoretical analysis and numerical simulation, the reasonable narrow coal pillar width of roadway driving along the roadway is researched. By analyzing the distribution of vertical stress and horizontal displacement of roadway under different width coal pillar and the relative displacement between roof and floor of roadway, Narrow pillar width. The field application shows that the width of the narrow coal pillar determined by the research is reasonable, which provides a basis for the determination of the width of narrow coal pillar along gob-side entry.
