| Abstract: | On the basis of strata pressure observation and analysing the performance of flat top support, GQT-1 type, tried in Cuijiagou Mine, the theoretical foundation of fiat top yieldable support used in actual mining roadway is inquired, on which a new flat top metal support yieldable in bidirection is designed and its mechanical properties are tested in laboratory. |
| Keywords: | flat top metal support actual mining roadway contractibility |
