动态开采过程中河堤内部水平移动规律研究

Study on Horizontal Movement Law Within Embankment During Dynamic Mining Process

文章利用sv30测斜仪获取了河堤内部水平移动值,通过分析得到了该地质采矿条件下的水平移动稳定距、稳定角以及超前影响距、超前影响角,用理论方法确定了不同深度开采地表水平移动曲线,得到了正错动区宽度与距地表深度之间的拟合关系式,实测规律与理论规律一致,并将该拟合关系式应用到河堤实际治理中,实践效果证明了该治理方案的正确性。

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.
