Abstract Key word: The rock layer moves the observation station; Surface migration estimate parameter;Must protect the well lane, the building, the water body and the railroad and so on, causes them to be exempt from or to be short the harmful effect which mines, reduces the hidden resource the loss, must study the rock layer which and the surface migration rule the derground working causes. Establishes the surface above 6206 working surfaces to move the observation station, through the measured data, calculates the submersion, the incline, the curvature, the level migration and the level distorts, draws the sinking curve, the inclined curve, the curvature curve, the level migration curve and the level elastic curve separately according to the computed result. According to draws the curve and the corresponding ultimate strain value extracts the boundary angle, the motion angle, to affect the angle in advance finally, biggest surface migration estimate parameters and so on sinking speed angle of lag, surface migration duration. Through to asked the parameter the appraisal analysis to complete to the Wang village coal mine 6206 working surface surface migration rule preliminary summaries. 选我的 加油
