根据二盘区西翼煤柱综采工作面实际地质情况,该采区共有9条空巷与工作面平行或交叉,有3处超高段高度达到5 m以上,为开采带来了很大的难度。为了安全高效并且最大限度的回收煤炭资源,该矿以二盘区西翼煤柱综采工作面为背景,对超高段支护方法、过空巷开采工艺等关键技术进行了研究分析,采用了架棚支护和搭顶铺底过空巷等技术手段,结果表明,该方法能够满足超高段巷道支护要求及综采工作面空巷开采的要求,为今后相似工作面过空巷及超高段支护提供了可靠的理论依据和实践基础。
According to the actual geological conditions of the coal pillar mechanized mining face in the west wing of the second panel, a total of 9 empty lanes are parallel or crossed with the working face in the mining area, and the height of 3 ultra-high sections reaches more than 5 m, which brings a great deal of mining Difficulty. In order to safe and efficient and maximize the recovery of coal resources, the mine in the second panel West Wing coal mining face as the background, the ultra-high section of support methods, mining technology and other key laneway technology research and analysis carried out using The results show that this method can meet the requirements of supporting of roadway in ultrahigh section and the requirements of open mining in fully mechanized mining face, High-grade support provides a reliable theoretical and practical basis.
