摘要
针对张集煤矿1110(3)综采面轨运联巷交岔点断面大,综掘机施工困难的特点,采用锚杆锚索支护技术,并结合顶板岩性局部变化的特性,有效地对交岔点及周边围岩进行了加固。在张集矿首次采用了跨度大于10 m的矩形断面支护方式,取得了较好的技术突破和经济效益。
Aimed at the feature of large intersection and working hard trouble in Zhangji Coal Mine 1110 （3） fully-mechanized coal winning, we adopt bolt and anchor cable technology and combined the feature of roof rock fixed the rock around the intersection. Now we adopt the supporting way of the span is greater than 10 m section, which has got better technology breakthrough and economic effect.
