摘　　要：煤层在工作面回采过程中,上覆岩层会形成"三带"(垮落带、裂隙带和弯曲下沉带)。"三带"高度的确定,可为煤矿的瓦斯抽采及防治水等提供重要理论基础。应用数值模拟及理论计算的方法对古矿15#煤回采工作面顶板"三带"裂隙发育规律进行研究。通过15#煤层"三带"分布研究,确定15#煤层的裂隙带最大发育高度,为9#煤层积水下渗的可能性和15#煤层建立抽采系统治理瓦斯合理性论证提供依据。In the extraction of mining face of coal seams, the overlying strata will form into ＂three zones＂（caving zone, fissure zone and bending subsidence zone）. Determine the height of the ＂three zones＂ can provides important theoretical basis for gas drainage and water control and prevention of coal mines. The methods of numerical simulation and theoretical calculations are applied to study on the law of fissure development of ＂three zones＂ in roof of 15#stope of Gushuyuan Mine. By the study on the distribution of ＂three zones＂ in 15#coal seam, the maximum development height of the fissure zone of 15#coal seam is determined to provide reasonable basis for the argumentation of the possibility of the water infiltration in 9#coal seam and the rationality of controlling gas of 15#coal seam by establishing drainage system.
