摘要:
为了揭示不同煤厚-煤柱宽配比条件(A-1∶2、B-1∶1、C-1∶4)底鼓差异性演化规律，采用理论计算、数值模拟与工程实测相结合方法开展塑性区宽度计算、应力—变形演化分析及治理验证。研究结果表明：煤柱宽度决定应力集中形式，窄煤柱诱发单一高强度应力集中，宽煤柱形成双应力集中；煤厚调控应力传递效率，薄煤体强化应力集中，厚煤体分散能量；采取治理措施后最大底鼓量降至126 mm，降幅达79%。研究结果可为深部沿空巷道底鼓防控提供参考。
Abstract:
In order to reveal the differential evolution patterns of floor heave under varying coal thickness to coal pillar width ratios (A at 1∶2,B at 1∶1,and C at 1∶4),a combined approach of theoretical calculation,numerical simulation,and field measurement is employed to conduct plastic zone width calculations,stress-deformation evolution analysis,and remediation verification.The results show that coal pillar width governs the form of stress concentration,where narrow pillars induce a single high-intensity stress concentration while wide pillars produce a dual stress concentration pattern.Coal thickness regulates stress transfer efficiency,with thin coal bodies intensifying stress concentration and thick coal bodies dissipating energy.Following the implementation of remediation measures,the maximum floor heave is reduced to 126 mm,representing a reduction of 79%.These findings provide a reference for the prevention and control of floor heave in deep gob-side entries.
