Chinese coal mine machinery industry took to hydraulic support
research and development from the late 1960s, and introduced dozens of sets of hydraulic supports
from the United Kingdom, Germany, Poland and the former Soviet Union in the 70s; after the trial use, imitation and lessons learned, the development and application of hydraulic support
gained rapid development in the 1980s, accompanied by successive development and production of over 20 different specifications of hydraulic supports
embracing TD series, ZY series and ZZ series.
