摘要
以鄂尔多斯市中北煤化工有限公司色连二矿12205工作面为例,分析综采工作面地表移动变形规律。结果表明:(1)丘陵地貌对开采沉陷规律的影响比较大;(2)凸形地貌在采动过程中地表产生滑移,导致坡顶附加下沉量与水平移动值小于两侧,造成边界角和移动角减小。
Taking the 12205 working face as an example in Selian No.2 Coal Mine of Ordos Zhongbei Coal Chemical Co.,Ltd.,the law of surface movement of the comprehensive working face was analyzed.The results showed that:(1)The hilly topography had a great influence on the law of mining subsidence;(2)Landform produced slippage during the mining process,which caused the additional subsidence and horizontal movement of the top of the slope to be smaller than the two sides in convex,resulting in the reduction of the boundary angle and movement angle.
