The Application of Large Mining Height Fully-mechanized Technology in Large Inclined Angle Working Face of Quandian Coal Mine

Ⅱ₁-14050 working face is the first large mining height fully-mechanized face in Quandian Coal Mine. It has the features of large mining height, large inclined angle and "three-soft". This paper analyzed and summarized the problems which were met when large mining height fully-mechanized technology is used in complex geological condition. The solution and measures are proposed, and high production and high efficiency is realized.
