论文摘要：本文主要介绍了含水层下条带充填间歇开采覆岩破坏规律。条带充填间歇开采是先将工作面分割成宽煤柱，然后再将宽煤柱分割成窄条带，按顺序先后掘进充填，再进行回采，依次在上循环条采带旁边布置回采条采带并进行充填。并以山东太平煤矿为例，采用现场实测、物理模型、数值模拟对比分析了条带充填间歇开采、连续充填开采以及垮落法开采的覆岩破坏及下沉规律。数值模拟和物理模型的结果表明，条带充填间歇开采的覆岩破坏高度和下沉值是最小的。数值模拟结果还表明条带充填间歇开采过程中采场的应力变化与现场实测结果一致。结果证明，条带充填间歇开采可以有效的减弱覆岩破坏和下沉、抑制突水溃砂。
Abstract: This paper presents an investigation on the effects of intermittent cut-and-fill mining on the overburden failure under sand aquifers. In the intermittent cut-and-filling method, the panel is divided into long pillars, then entries in every long pillar with a narrow strip; every narrow strip is then cut and backfilled. Field measurements, scale model tests and numerical simulations are used to compare overburden failure and subsidence due to three mining methods: intermittent cut-and-fill mining, longwall excavation and continuous filling. These methods were applied in a case study of the Taiping Coal Mine, in Shandong, China. The results of the numerical simulation and scale model testing reveal that the height of the maximum caving and water-conducting fractured zones, and the maximum subsidence due to intermittent cut-and-fill mining are much smaller than those with the use of longwall excavation and continuous filling, and well verified by the field measurements. Additionally, the numerical simulation results of the stress distribution and variation during intermittent cut-and-fill mining are in close agreement with those of the field measurements. It has been proved that the intermittent cut-and-fill miningcan successfully mitigate the overburden failure and subsidence, which contribute in preventing water and sand inrush into coal mines under sand aquifers. This provides a less costly and more effective approach to address surface subsidence and mine caving problems.
Key Words: sand aquifers; intermittent cut-and-fill mining; overburden failure; fractured zone; caving zone; subsidence.
