Abstract: According to the analysis results of geological conditions coal seam and its law of mine pressure,the roadway layout scheme and equipment matching way of 415 working face are researched.The research results show that,the continuous miner short-wall complete sets of equipment has good adaptability to slowly inclined thick coal seam.The characteristics of mine pressure of short wall working face is similar to long wall working face and the first weighting and periodic weighting are existed.Therefor,the research results of this paper lay a foundation to expand the application range of the continuous miner and provide guidance for the short-wall mining method of the similar coal seams.

Key words: Inclined thick coal seam, Continuous miner, Slowly inclined thick coal seam, Short-wall mechanized mining method, low of mine pressure
