大倾角综采工作面液压支架稳定性分析

摘要

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 .%液压支架在大倾角工作面条件下，由于支架的重心方向与支护阻力方向形成较大夹角，支架会产生下滑的分力，同时支架的重心方向可能偏出支架的底座，由此产生支架歪倒的可能性。本文通过对赵各庄矿业公司3372大倾角综采工作面液压支架稳定性进行研究，分析了大倾角综采工作面的顶板运动规律及支架的受力情况。提出了工作面液压支架相应的防倒防滑改进措施，为实现3372大倾角综采工作面安全高效的回采提供了理论依据。
