In combined with the first support actual conditions of the deep mine roadway, the pa- per provided the secondary reinforced support design parameters of the mine roadway.

A case analysis for foundation pit support reinforcement of a commercial/residential complex in Changsha;

The design of support reinforcement of an eastern side slope of a transformer substation in Changsha city was introduced,and the slope stability was analyzed.

Finally,some reasonable recommendations for the reinforced supporting are put forward as well.

11-2Coal seam in need of reinforced supporting in Coal Mine of Tang Shan Gou,its complex roof conditions were analyzed.

Study on laneway excavation monitoring and best secondary support time with new austrian tunnelling method;

In order to determine the secondary support time and intensity,the changing rules of the stress and deformation speed of surrounding rocks with time,the effects of the secondary supporting time and intensity of surrounding rocks on deformation were analyzed using exponential creep model of FLAC2D at west tunnel in the Guhanshan Mine of Jiaozuo Coal Industry Group.

Ground reinforcement of the connecting aisle is finished successfully through strictly controlling key construction measures such as freezing holes construction,freezing station installation and secondary support.

Practice of second support theory applied to deep mine soft rock section chamber support;
