| 摘 要： | 近距离煤层开采后，上下层工作面之间将产生相互作用。上下层工作面的合理错距是一个重要工程参数，它直接关系到上下层间的作用。采用离散元法对一个实际条件进行了模拟，分析了互层作用，确定了合理的错距，为安全生产提供了依据。

| Abstract: | The interaction between upper and lower mining faces occurs while mining multiple seams. The determinnation of the distance between the two faces is a key problem in coal mining and has direct impact on the interaction between seams. Based on the practical conditions,the discrete element method has been used to study the phenomenon of seam interaction. The numerical simulation is in good coincidence with that observed in coal mining practice. |
