摘要
以现场实测资料为基础,通过实验室相似模拟试验对浅埋深条件下厚煤层的顶煤冒放性问题进行了研究,以确定采用放顶煤采煤法的可行性,对类似工程实际有一定的现实指导意义。
With means of a similar simulation model experiment, caving characteristics of the thick coal with shallow earth cover are studied. Consequently the possibility that the adoption of the top coal caving could be confirmed, which has a reference significance to similar operations.
