不稳定“三软”厚煤层综放开采矿压显现规律相似模拟研究
Simulating study in the strata behavior under the fully mechanized top caving of the unstable “three soft”thick coal seam
为了掌握不稳定“三软”厚煤层放顶煤开采时的矿山压力显现规律，根据邢台显德汪矿9#煤层的工程地质和开采技术条件，采用相似模拟实验的方法进行研究，并且对首个综放工作面进行了常规矿压观测，研究结果与现场实测结果非常吻合，为现场的顺利开采提供依据，对同类条件下放顶煤工作面开采具有指导意义。
In order to master the strata behavior of the unstable “three soft” thick coal seam during top caving,according to the conditions of the mining engineering geology and mining technology of Xingtai Xiandewang # 9 coal seam,using the similar simulation-based experiment for researching,and observing the strata behavior of the first caving face,finanlly the analyse results are identical with the observing point. It provides a basis for successfully mining,and it will be instructive and meaningful to the similar conditions of the top caving face.
