浅部松散含水层下开采上“两带”观测与相关规律研究

针对煤层露头附近开采，对上覆岩层造成的破坏程度的问题，采用钻探、物探以及地表沉陷观测，进行了导水裂缝带发育高度和地表岩移规律研究，取得了浅部松散含水层下开采引起覆岩变形破坏及地表沉陷规律，得出了垮落带、导水裂隙带（简称上“两带”）发育高度及地表沉陷的主要参数。对煤矿浅部松散含水层下开采的水害防治工作及安全生产具有重大意义。

Research on "upper two zones" observation and related laws of mining under shallow loose aquifer

Aiming at the problem of the degree of damages caused by the coal seam outcrop and the damages caused by the overlying strata，using drillings，geophysical and surface subsidence observations，the researches on the development height of the water-conducting fracture zone and the surface rock movement law were carried out.The deformation and failure of overburden and the law of surface subsidence caused by mining under the shallow loose aquifer have been obtained，and the main parameters of the development height and surface subsidence of the fault zone and the water-conducting fracture zone（referred to as the "two belts"） were obtained.It is of great significance to the prevention and control of water disasters and safe production under the loose aquifer in shallow coal mines.
