Study on Design Types and Adaptability of Anchor Truss

Anchor truss support technology is an innovative technology in support theory, and it could give vertical and horizontal force to roadway roof. In the process of its popularization, several design forms were used to coal mine; we introduce four kinds of active control principle including simple anchor truss, anti-symmetrical arrangement control technology, embedded and composite-active control technology. Each technical characteristic was analyzed and the adaptability to different section was reached.
