摘要
在掘进机局部大倾角掘进或过断层期间需抬坡掘进时,拆除掘进机第二运输机,在输送机机尾处安装耙装机,掘进机破煤矸后将煤矸积存在耙装机与掘进机之间,垫高掘进机减缓掘进机机身倾角,实现大倾角掘进。
When the roadheader needs to raise the slope when driving at a local large angle or passing through a fault,the second conveyor of the roadheader is removed,and a harrow loader is installed at the tail of the conveyor.After the roadheader breaks the coal gangue,the coal gangue is accumulated between the rake loader and the roadheader,and the roadheader is padded up to slow down the inclination angle of the roadheader body,so as to realize the large angle excavation.
