摘要
为了使锚杆和锚索形成同步受载,从而到达主动支护、均压的目的,通过对兴县金地煤业地质条件的综合研究分析,合理设计出适合厚煤层沿底板巷道掘进的支护方式和支护参数,运用耦合让均压的技术,增强巷道支护强度、控制巷道变形,同时放大掘进棚距,提高单进水平。
In order to synchronize the anchor rod and anchor rope under load, so as to reach the active supporting, equalizing goal, through the comprehensive research and analysis of geological condition in Jindi Mine, a reasonable thick coal seam roadway drivage along the bottom supporting method and support parameters were designed. The coupling equalizing technology enhanced the strength of support and control the deformation of roadway, enlarged drivage shed distance and improved the single mining level.
