煤炭科学研究院北京开采所从美国CV公司引进的我国煤炭行业第一套大型液压支架计算机辅助设计系统,于1986年12月通过了国家验收鉴定,正式投入使用。这套系统可以缩短支架设计周期,提高设计质量,改进支架性能,降低成本,加快架型更新,具有重要的技术和经济意义。该系统能满足煤矿支架、采掘机械、井巷工程计算机辅助设计需要,还能满足工业与民用建筑计算机辅助设计需要。 Coal Mining Research Institute of Beijing Mining from the United States CV company introduced China’s coal industry’s first large-scale hydraulic support computer-aided design system, in December 1986 passed the national acceptance, officially put into use. This system can shorten the design cycle of the stent, improve the quality of the design, improve the stent performance, reduce the cost and speed up the frame renewal, which has important technical and economic significance. The system can meet the needs of computer aided design of coal mine support, mining machinery and roadway engineering, as well as meet the needs of computer aided design of industrial and civil buildings.
