原燃化部于1974年12月4日至9日在大同矿务局召开了TZ-1型液压支架技术鉴定会。该支架是由山西煤炭工业研究所和大同矿务局在我国第一个全工作面试验的TZ-140型液压支架(此支架经过三年多的井下试验和多次总结、改进、重新修改设计)的基础上设计,由大同矿务局机修厂制造成功的,其中控制阀、操纵阀、管接头由无锡煤矿机修厂制造,橡胶件和塑料件分别由西北橡胶工业制品研究所和四川晨光化工厂研制;支架用的工作液为煤炭科学研究院北京研究所、石油化工研究院、苏州炭黑厂和上海炼油
The former Ministry of Combustion was held December 4, 1974 to 9 in Datong Mining Bureau held TZ-1-type hydraulic support technology appraisal. The scaffold is a TZ-140 type hydraulic scaffold that was tested by Shanxi Coal Industry Research Institute and Datong Mining Bureau in our first full face test. After more than three years of downhole test and multiple summarization, the scaffold has been improved and redesigned ) On the basis of the design, Datong Bureau of Mines manufactured successfully repair shop, in which control valves, control valves, pipe joints manufactured by Wuxi Coal Mines, rubber and plastic parts from Northwest Rubber Industrial Products Research Institute and Sichuan dawn Chemical Plant development; stent with the working fluid for the Beijing Institute of Coal Research Institute, Institute of Petrochemical, Suzhou, black plant and Shanghai Refining
