国家“七五”科研攻关项目EBZ-75型横轴可伸缩式半煤岩掘进机,于1991年10月23日在唐山通过部级鉴定。EBZ-76型掘进机是院厂联姻的攻关成果,1986年由煤科总院唐山分院研究设计,1987年国营内蒙第二机械制造总厂生产制造。经过五年的实践证明,该机总体布置和主要参数选择合理,加工工艺基础可靠,制造质量较好。该机通过半煤岩巷道掘进综合机械化作业工业性实验,三个月累计进尺1030.4m,最
The national “Seventh Five-Year” scientific research project EBZ-75 horizontal axis telescopic semi-coal rock roadheader, in October 23, 1991 in Tangshan passed ministerial level appraisal. The EBZ-76 boring machine is the result of the marriage of hospital yard. In 1986, it was researched and designed by Tangshan Branch of Coal Science Institute and was manufactured by State-owned Second Machinery Manufacturing Plant in Inner Mongolia in 1987. After five years of practice has proved that the aircraft layout and the main parameters of the overall choice of reasonable, reliable processing technology, manufacturing quality is better. The machine through the semi-coal and rock roadway mechanized operation of industrial experiments, the cumulative total footage of 1030.4m, the most
