为了掌握晋煤集团赵庄二号井厚煤层综放工作面顶煤运移规律，以首个综采工作面1304工作面为工程背景，运用深基点位移法进行现场实测。结果表明：顶煤始动点随煤层位的不同而变化，顶煤层位越高始动点位置越超前，顶煤运移始动点发生在煤壁前方15~20m位置；顶煤从始动点至煤壁位移量远大于煤壁至顶煤冒落的距离；工作面顶煤运移煤壁前以水平运移为主，工作面煤壁后方以垂直运移为主。研究结果为确定合理的放煤工艺参数，提高顶煤回收率提供参考。
為瞭掌握晉煤集糰趙莊二號井厚煤層綜放工作麵頂煤運移規律，以首箇綜採工作麵1304工作麵為工程揹景，運用深基點位移法進行現場實測。結果錶明：頂煤始動點隨煤層位的不同而變化，頂煤層位越高始動點位置越超前，頂煤運移始動點髮生在煤壁前方15~20m位置；頂煤從始動點至煤壁位移量遠大于煤壁至頂煤冒落的距離；工作麵頂煤運移煤壁前以水平運移為主，工作麵煤壁後方以垂直運移為主。研究結果為確定閤理的放煤工藝參數，提高頂煤迴收率提供參攷。

In order to grasp the Shanxi Coal zhaozhuang II wells Thick Coal Seam Top Coal shift law, the first fully mechanized coal face to face in 1304 as engineering background, deep-site basis points measured using the displacement method. The results show that:the beginning of the top coal seam bit fixed point with different changes, the higher the top seam bit more ahead of the initiating point, the top coal initiating point shift occurred in the coal wall in front of 15~20m position;top coal from initiating point to the coal wall displacement is much larger than the amount of coal wall to top coal caving distance;former top coal face in the wall to move the horizontal transport of coal-based, face the wall behind the vertical transport of coal-based. The results for the determination of reasonable caving process parameters, increase the top coal recovery rate reference.
