采煤工作面大倾角液压支架的研究

Study on the hydraulic support of coal mining face with large dip angle

在大倾角开采条件下,液压支架会发生下滑,严重时会导致支架倒塌,支架阻力也达不到要求。掌握大倾角工作面顶板运动的规律和支架阻力分布,分析大倾角工作面支架分布特征及其适应性,保证支架发挥最大程度的阻力,切实保证施工的安全性和可靠性。

Under the condition of high dip angle, the hydraulic support is easy to decline, and it will lead to the collapse of the support and the support resistance can＇t reach the requirement, it is necessary to master the law of roof movement and support resistance distribution of working face with large dip angle, analyze the support adaptability and the distribution characteristics of large dip angle working face, ensure the support resistance in the maximum degree, and ensure the safety and reliability of construction.
