Abstract: Mechanization retracement technology applying to working face can effectively promote the retracement rate, and the 1201 working face with mechanization retracement technology solves problems such as large dip angle, soft floor, high risk of fire preventing and extinguishing, high labor intensity and low working efficiency, and realizes the transportation safety, easy direction adjustment and simple loading for large dip angle of 26°. In addition, both retracement safety coefficient and retracement rate are promoted, offering practical experience for the application of large dip angle working face equipment in similar conditions.
