摘要
根据唐口煤矿深部采煤工作面地质及回采技术特点,建立了UDEC数值计算模型,对工作面覆岩的应力、位移、塑形变形区等参量展开了系统研究。模拟结果显示,在1307工作面回采影响下,导水裂缝发育高度达到48.1 m,冒落带高度为14.6 m。
According to the geographical and technical characteristics of deep mining face of Tangkou mine,the UDEC numerical model was established,the overburden stress,displacement and plastic deformation had been studied. Simulation results show that：under the influence of the 1307 mining face,the height of water flowing fracture was 48.1 m,the height of the caving zone was 14.6 m.
