三掩护支架及三角区支护配套撤架技术研究

Research on the Support Removal Technology of Three Shield Support and Triangle Support

为了解决以往撤架工艺中三角区空顶面积大、支护强度弱、人员作业区域安全隐患大等问题,采用“三掩护支架及三角区支护[1]配套撤架技术”替代“双掩护支架”[2]撤架工艺,该工艺在8310工作面应用成功,实现了支架的顺利撤出,避免了压架事故的发生。

In order to solve the problems of large empty roof area in triangle area,weak support strength,and large potential safety hazard in personnel operation area in the previous support removal process,"three shield support and triangle area support[1]supporting support removal technology"is adopted to replace"double shield support"[2]support removal process.The process is successfully applied in the 8310 working face,which realizes the smooth withdrawal of support and avoids the occurrence of frame pressing accident.
