回采工作面过极近距离空巷采煤技术研究

Research on Mining Technology Used in Passing through Abandoned Roadway with Extremely Close Distance at Backstopping Working Face

辛置煤矿310水平一采区2-110工作面扩增优化圈定产量后,区域内留存有一因变形严重无法使用的2-108正巷(现2-110空巷)。为保证过空巷期间的安全生产,针对过空巷时出现的技术难题,并综合以往各类过空巷经验,按照空巷与切巷的层位有针对性地制定了不同阶段过空巷的措施。

The main transportation roadway 2-108 （now 2-110 abandoned roadway） was left behind due to severe deformation after increasing optimizing production delineation at 2-110 working face in 310 level 1st mining area of Xinzhi Coal Mine. In order to ensure the safety in production during abandoned roadway use, targeted measures at different stages tor passing abandoned roadway with regard to the position of abandoned roadway and roadway in open-off cut were formulated according to technical problems in abandoned roadway and all kinds of related experience.
