Application of prestress truss cable in large cross section coal roadway;

Technology of the truss cable combined support on large cross-section compound mudstone roof starting cut;

The truss cable support technology at the large cross-section set-up room with thick and broken coal roof

Analysis of a stayed-cable plane truss using equivalent linearization method showed that the matrices established with both methods were of high similarity,implying that the method we set up in the present was effective and could be applied to .

The use of plane truss in frame design;
