Study on Horizontal Movement Law Within Embankment During Dynamic Mining Process

The s242sv30 clinometer was applied to get the horizontal movement value within the embankment.With the analysis,the horizontal movement stabilized distance,the stabilized angle,the pilot influence distance and the pilot influence angle under the geological mining conditions were obtained.The theoretical method was applied to determine the surface horizontal movement curve caused by the different depth mining and to obtain the fitting relational expression between the width of the positive dislocated zone and the depth from the surface ground to the mining seam.The actual measured law and the theoretical law could be the same.The fitting relational expression was applied to the actual control of the embankment and the practices effect showed the correctness of the control plan.
