CONTROL DESIGN OF ROOF ROCKS FOR GOB-SIDE ENTRY
沿空留巷顶板岩层控制设计

The motion process and deformation characteristics of roof rocks are analyzed for gob side entry and the function of roadside packing support during every stages of roof rock motion becomes clear. On the basis of interaction between packing support and roof rocks, the control design principle of retaining roadside packing supporting intensity is decided for gob side entry during each stage, and the mathematics model of support resistance and rational compressed volume is established.
