摘要
针对悬移支架放顶煤工作面过石门对安全岩柱的确定、石门充填长度的确定、充填加固方式等技术要素进行了论述,总结了跨石门期间工作面所采取的主要安全技术措施,合理、有效地确保了悬移支架工作面跨石门的回采安全。
This article elaborates the determinisms of security rock pillar, backfill length and the way of backfill reinforcement by using support hangs moving, and summarizes the main safety work measures which crossing the working surface. This technology reasonably and effectively guarantees the security when crossing working surface by support hangs moving.
