摘　　要：利用全景摄像系统,通过井下分段注水试验,探测开采余吾煤业工作面冒落带高度情况,并利用相似模拟和数值模拟对冒落带高度发育情况进行了模拟。研究结果表明:上覆岩层冒落带的高度在28.6～31.0m,对所有结果综合进行拟合,得其拟合曲线为:y=-0.085 88x2+5.82x±6.1。The segmented panoramic camera system and underground injection test were used to detect the height of caving zone on working face of Yuwu Coal Industry Co. ,analog simulation and numerical simulation were also used to simulate the development of ca- ving zone. Results show that ： the height of overburden caving zone is between 28.6 - 31.0 m,and the complete fitting was made based on the data obtained,then the fitting curve was drawn,that is ：y = - 0. 085 88x2 ＋ 5.82x =l： 6.1.
