| 摘 要： | 借助相似材料模拟试验的研究方法, 讨论了华亭矿区白草峪井田煤5 特厚煤层的放顶煤问题。试验认为: 分3层放顶煤的开采方法是可行的, 分2 层放顶煤的方法是不可行的; 分3 层放顶煤时回收率能够达到要求, 而分2 层时回收率较低。同时也得出放顶煤的最佳分层厚度为12～15 m , 最佳采放比为1∶3 。以上结论为白草峪井田的开采设计提供了重要依据。

| Abstract: | With the help of the research methods of similarity model tests, the problems about top coal caving of specially thick coal seam of coal No.5 of Baicaoyu well field in Huating mine administration is discussed. Three similar material model tests show that the top coal caving mining with three layers is reasonable, but the top coal caving mining with two layers is not reasonable. The coal-recycling ratio with three layers can meet engineering requirement, but the coal-recycling ratio with two layers is very low. The optimal layer-divided thickness is 12～15m and the optimal ratio of mining to caving is 1∶3. |
