摘要
在分析崔家沟矿试用GQT-1型平顶形支架性能及矿压观测基础上,探讨了平顶形支架在回采巷道应用的理论根据,据此设计出新的双向可缩双跨平顶形金属支架,并对其进行了力学性能试验。
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.
