The terminated research programme was based on the following aims: Mechanization of roof support setting; parallelism of roof support setting with cutting and loading procedure; improvement of roadway stability. The roadheader E 250 embodying a novel swing link mechanism was developed in the scope of the research programme. The successful trials of the machine and the swing link mechanism took place at the Walsum colliery in 1989 where the best monthly rate of advance came up to a total of 259 m within 20 working days, i.e. 12.95 m/d as an average. The best rate of advance per day was approximately 18 m. This has confirmed that the swing link mechanism considerably improves the efficiency of roadheading machines when driving roadways, espec...
