Abstract: In the large inclined coal face it is easy to appear the phenomenon that influence safety production, such as hydraulic support slipping and dumping, scr aper conveyor down, bulk coal gangue roll down along the scraper conveyer and so on.Therefore, overall stability of the equipment and reasonable security technology measures are the premise of normal production in large inclined coal face.In the process of practice in the large inclined coal face 22031 of Lugou Mine. Based on theor etical calculation and field analysis, by using whole trimmer beam plus five column support plus oriented restrictions beam measure, the problems like hydraulic support slipping, slanting were solved;By using pull the top, butt the bottom and leading chain measure, the problem like scraper conveyor down was solved;By using plate for C ontrolling rolling gangue plus retaining gangue chain plus retaining gangue plate measure, the problem like bulk coal gangue roll down along the scraper conveyer was solved, which can provide feasible technical support for large inclined coal face safety production.
