摘要:
A method of steering a double-ended ranging drum mining machine including the steps of positioning a first current cut roof follower at or adjacent the center of the machine and measuring the machine tilt by a second sensor. The coal thickness is estimated by using a third sensor and the data gathered is used in generating algorithms therefrom whereby the height differences between points on the current cut roof can be calculated to control and steer the leading and trailing cutting drums. The algorithms are generated in such a manner that cumulative errors along or towards the face are minimized or eliminated.
