| Abstract: | Base on the site conditions in Yujialiang Mine,the paper introduced the measurement principle,the measuring method and the measuring procedure of the released circle.With the measurement,the rational released circle scope of the surrounding rock was obtained,which could provide the basis to set up the rational bolt support parameters and could provide the practical experiences for the released circle measurement in the similar mine roadway conditions.The paper introduced the method to control the released c... |
| Keywords: | surrounding rock released circle mine roadway bolt support |
