断层性质对轻放开采顶板影响程度研究

Study on Influence Extent of Fault Nature to Roof in Light Caving Mining

东荣三矿地质条件复杂,断层多,这也是轻放工作面过断层面临的一项非常重要的开采问题。要解决这一问题,必须对断层性质影响轻放工作面顶板的程度进行深入研究。

The geological conditions are complex,and the number of faults are more in Dongrong No.3 Coal Mine.This is a very important mining issue through faults at the light caving face.In order to solve the issue,the influence extent of faults nature to the roof of light caving face must be studied in-depth.
