摘要
弘泰福源矿业有限公司201采区煤层倾角35-60°，平均为50°，属急倾斜煤层。矿井采用伪倾斜柔性掩护支架采煤法开采，将煤层倾角降低到25-30°，将急倾斜煤层变成了缓倾斜煤层来开采，取得良好效果。
In Hong Fu Yuan Mining Co. 201 mining area, coal seam dip angle of 35 degrees to 60 degrees, the average is 50 degrees, is a steeply inclined coal seam. using false inclined lfexible shield mining method reduced the coal seam dip angle to 25 to 30 degrees, become the steeply inclined coal seam mining into gently inclined coal seam, and achieved good results.
