Adjustment of mine conveyor angle by link with mine roof support

摘要

The mine roof support 10 has an advancing mechanism 12, 13, 16, for connecting the mine roof support to an abutment, for example a mine conveyor 18. Adjustment means 25, 26 is connected between the mine roof support and the conveyor for adjusting the angle of the conveyor with respect to the mine roof support. This in turn makes it possible to adjust the orientation of a mining machine (30 Fig. 2 not shown) mounted on the conveyor 18, with respect to the mine roof support. This makes it possible to reduce the risk of the mining machine 30 colliding with a roof engaging portion (33 Fig. 4 not shown) of the mine roof support, particularly in high seams. IMAGE
