In this thesis, Jizhong Energy Fengfeng Group on Urban Coal Seam IV13 201 fully mechanized coal face as engineering background, through computer simulation and field measurement and other research methods, compression characteristics and surrounding rock control of mining face in high inclined seam mining process techniques were studied.Through computer simulation seam mining different inclinations were studied in high inclined seam during mining face in the direction and the vertical stress distribution as well as the tendency of fully mechanized mining face in high inclined seam mining in the mine when the apparent pressure characteristics.According to field test, analysis of high inclined seam mined at the mine pressure behavior law; through the collection of information, reading relevant literature books, apply relevant theoretical knowledge, analysis of steeply dipping seam mining of ore rock pressure features and Faces migration law.In order to obtain high inclined seam mining face when mining pressure behaviorbased, while the stability of the fully mechanized coal face equipment big dip and 201 mechanized mining equipment selection analysis and study, presented in high inclined seam of surrounding rock control technologies.
