Abstract：the hydraulic support big dip in tilt mining working condition , the result of stents not the center of gravity of the direc-tion and support resistance direction Angle formed bigger , stents, will produce the decline of reality , and the center of gravity of the stent direction may wide from the base of the stents , which produce stents slanting down , support working resistance enough play the possibility.This article through to the zhaogezhuang mineral industry company 3372 big obliquity of fully mechanized working face of hydraulic support stability , analyzes the fully mechanized working face big dip roof movement rules and support 's stress.Put forward the hydraulic support the corresponding prevention measures to prevent slippery fall , to achieve 3372 Angle fully mechanized working face safely and efficiently provide theoretical basis for the recovery .
Keywords：Angle fully mechanized working facestabilityPrevent fallanti-skidding
