| Abstract: | The four-four line arrangement of single hydraulic supports represellts a newly developed roof arrangement based on three-four line and four-five line arrangement. The arrangement combining the advantages of three-four and four-five line arrangements marks a reform centered on cutting technique. Many years' practices have proved that the arrangement can afford greater safety,higher efficiency, less cutting operation and lower costs. |
