Abstract:
Based on the site conditions of 2313 deep inclined fully mechanized top-coal caving face of Geting Mine, by establishing and analyzing the mechanical model of hydraulic support, the paper proposes the critical influencing factors and control measures of dump, sliding and crook of the supports. Under no-restriction conditions, anti-sliding measures should be taken in the hydraulic supports of mining face with dip angle of more than 16°, while anti-dropping measures more than 29°. The technical measures have been applied in geting mine, which realized the safe and high-efficiency exploitation in the greater inclined full mechanized wall with the average inclination of 36°, maximum inclination of 51°.
