In order to address the floor heave issue during the mining of fully mechanized top-coal caving faces in ultra-thick coal seams, the floor heave mechanism was investigated through field investigations, theoretical analysis, and numerical simulations. Corresponding control technologies were proposed. The ZF1409 working face in a coal mine in Shaanxi province was selected as the engineering case. Key findings include: Severe floor heave predominantly occurs during periodic weighting periods. Higher shield support resistance is observed, particularly in areas with mudstone-dominated floor strata or thin residual coal beneath the floor. The sliding surface of the floor stratum primarily consists of weak mudstone with low ultimate bearing capacity. Floor heave initiates when the applied load exceeds the ultimate bearing capacity. The frictional resistance and cohesion generated by the self-weight of the rock mass along the sliding surface are overcome. Numerical modeling of the ZF1409 face reveals that shield support resistance plays a critical role in floor heave evolution. Under fully mechanized top-coal caving conditions in ultra-thick coal seams, the sudden rupture of the near-field key stratum forms a cantilever beam structure, causing rapid escalation of shield resistance and subsequent floor heave. Implementing underground regional hydraulic fracturing technology to precondition the near-field key stratum effectively mitigates floor heave by optimizing stress redistribution.

为解决特厚煤层综放工作面回采期间工作面底鼓问题，以陕西某矿ZF1409工作面为工程背景，采用现场调研、理论分析与数值模拟等方法，探究特厚煤层综放工作面底鼓机制，并以此提出底鼓控制技术。结果表明：工作面严重底鼓区域主要集中在工作面来压期间，支架工作阻力较大，且底板大多为泥岩或底煤较薄的区域；底板滑动面范围内以软弱泥岩为主，底板极限承载力较低，当底板载荷大于底板极限承载力时，底板载荷克服底板滑动面范围内岩层自重所产生的摩阻力及黏聚力，使岩体沿着底板滑动面滑移，造成工作面底鼓；通过分析ZF1409工作面底鼓模型可知：支架载荷在该工作面底鼓发生过程中起到了重要作用；特厚煤层综放开采条件下，近场关键层破断形成的“悬臂梁”结构造成支架工作阻力在短时间内急剧升高，导致工作面发生底鼓。基于此，采用井下区域水力压裂技术处理近场关键层，有助于控制工作面的底鼓。
