摘要
抚顺矿区煤层厚度平均为 5 5m ,属特厚煤层 ,且抚顺矿区属冲击地压多发和强冲击地压显现严重地区 ,抚顺老虎台矿冲击地压下特厚煤层煤巷锚杆支护通过试验已取得初步成效。
The coal bed thickness of Fushun diggings is about 55 meters belongs to extra thick coal beds.Fushun diggings is such a area that impact ground pressure occurs very often and apears very badly.In Fushun Laofutai Coal Mine,the experimental study of application of bolting to the impact ground pressure zone of extra thick coal beds is obtained succefully.
