Abstract :
Aimed to dissolve the question that it is difficult to maintain the developing entry during mining in the weak and fragmentized ore body, carried out the site monitoring, convergence monitoring and numerical simulation to disclose the distortion mechanism of developing entry of chengchao Iron Mine. the data provide the support for the preparatory workings deformation mechanism. the result of the monitoring and numerical simulation indicated that the displacement of preparatory workings is relative to mining course, and the displacement increase with the depth increase. The result is to provide a theoretical support to choose the system of protecting synthetically in deep mines and the right time of support..
