影响大采高综采支架稳定性的试验研究

Research on influencing factors of tilt for fully-mechanized mining support with large mining height

在自制的支架试验台上进行了支架在多因素条件下的横向倾倒与滑移试验。结果表明 ,倾角、采高、重心高度、移架顺序等对支架横向倾倒和滑移都有明显影响 ,并给出了影响程度排序 ;

Tilt test for the support was performed on comprehensive test bench under the conditions of various factors.It shows that dip angle, mining height, height of gravity center, and sequence of support movement have influences on tilt of the support significantly.The sequence of influenced extent is given and correlation relationship between various factors and stability of the support is approached.
