Abstract: This paper expounds the soft coal roadway in soft coal seam and the basic concept of plateau environment and the characteristics of the deformation of supporting scheme. The Jiangcang mine four mine 2013 working face in soft seam track trough as the researches on the supporting scheme of object, research and field tests on 3 different support way of. The anchor net +U type roof support, Bolt Mesh Cable + T strip, advance + anchor grouting Cable + T steel. Through the comprehensive mine pressure observation results show that: Advanced + anchor grouting cable tunnel support + T type steel most suitable for plateau soft coal seam.
