摘要 分析了大采深厚煤层条带开采的采动覆岩与地表移动变形机制,结合鹤壁九矿二五采区条带开采实例,通过相似材料试验模拟,揭示了大采深厚煤层条带开采上覆岩层的破坏过程及移动变形规律,研究了煤柱压缩量和地表下沉系数的影响因素及其变化规律。 The mechanism of mining- affected subsidence and overlying strata and ground movement induced by mining of great mining depth and thick seam with strip - partial mining has been studied. The rationality and reliability of strip mining plan and parameter se lection has been proved by similar material test simulation in the 25 mining area of Hebi nine coal mine. The damage process of overburden strata, the laws of movement and deformation are found out. The influencing factor and changing law of strip pillar decrement and surface subsidence coefficient has been studied.
