| 摘 要： | 杨村煤矿薄煤层综采工作面地质条件复杂,煤层中普遍含有椭圆状、硬度较大(f=8～11)硫化铁结核体和硬质夹矸,可采范围内共揭露14条断层且断层落差大、分布相对集中,由于该面布置为不规则梯形块段,存在缩面和延面现象,通过采取相应措施,有效地提高了薄煤层工作面的生产效率,该面成功回采的经验,对今后薄煤层的开采具有很好的借鉴作用。

| Abstract: | The surface of Yangcun Coal Mine fully mechanized coal mining face in thin coal seam,geological condition is complex,coal-bed generally containing elliptical shape,rigidity(f = 8-11) iron sulfide node core and hard partings,recoverable range to expose 14 faults and fault throw big,relative concentrated distribution,because the surface is arranged irregular trapezoid block,presence of shrinking face and extension of surface phenomenon,through taking corresponding measures,and effectively improve the working face of the thin coal seam mining production efficiency,the successful experience,for the future of thin seam coal mining has a very good reference. |

| Keywords: | thin seam mining process reduction of surface technology extended surface technology Crossing over fault a combination of iron sulfide and hard partings |
