特殊条件下辅巷多通道支架回撤技术

Supports retracement technology of auxiliary roadway and multi-crosscut under special conditions

为了实现特殊条件下综采工作面液压支架的安全、快速回撤,通过对石圪台煤矿31201综采工作面压死液压支架回撤技术的分析,对辅巷多通道回撤技术中的压死支架处理、炮眼布置、回撤通道起底等方面进行了改进。实践证明,该技术应用效果良好。

In order to realize hydraulic supports safety and rapid retracement of fully mechanized mining face in special con -ditions, the retracement technology and crushed supports in №31201 working face of Shigetai coal mine was analyzed and the improved plan for the treatment of crushed supports , the layout of blast hole and the maintenance of retracement crosscut was proposed .The practice shows that the effect of this technology is well .
