In order to study the overburden strata failure law and water conducted fracture zone development law under the condition of the fully mechanized top coal caving mining in Lu \'an Mining Area,three high level survey boreholes in the roof caving zone and the water conducted fracture zone were made in the 6206 fully mechanized top coal caving mining face in Wangzhuang Mine.
为了研究潞安矿区综采放顶煤条件下覆岩破坏规律和导水裂缝带发育规律,在王庄煤矿6206综放工作面施工了3个"两带"高度观测孔,进行了系统的观测研究,取得了冒落带、导水裂缝带发育高度,求取了预测导水裂缝带最大高度的经验公式。
补充资料：综采放顶煤
综采放顶煤：厚煤层煤炭开采技术之一。把原来分层开采的煤炭，一次采完。方法是，在煤层底部按传统方法开采，使上面的煤炭在矿压的作用下，自动落下来。
