摘　　要：通过结合淮北矿业集团有限公司朱仙庄矿 84 13- 2工作面的综放开采实践 ,利用深基点跟踪观测法 ,探讨了“三软”中厚煤层在予采顶分层情形下综放开采时顶煤变形运移特性 ,对类似地质条件的“三软”Since 1982, China began to introduce a fully mechanized coal mining technology from other countries. After a passed dozen years of application and development, the fully mechanized mining method has become a main access to a safe, high production and high efficient method in China coal mines with thick seam. As a new mining method for a longwall mining in thick seam, many new questions, such as a production system, strata control, safety technology and others have set to the previous coal mining method. Does a three soft thick seam can be suitably mined with a fully mechanized coal caving mining method? How is the top coal movement and displacement when a fully mechanized caving technology applied? After a fully mechanized caving practice in No. 8413 2 coal mining face in Zhuxianzhuang Mine, a top coal movement and displacement law was obtained. With deep base point tracing measurements, a working resistance of each hydraulic powered support in the coal mining face was analyzed and studied. A relationship between the top displacement curves and advancing rate in different location was obtained.
