1990年5月18日,中国统配煤矿总公司技术发展局组织通过了刚性井筒装备6.0m层间距的研究成果函鉴。这项研究成果是由中国矿业大学建筑系和兖州矿务局37工程处共同完成的。在年设计能力为4Mt的东滩煤矿主井井筒装备施工中,兖州局37工程处提出了罐道梁层间距由4.0m增大到6.0m的建议.经兖州煤矿设计院认可后实 On May 18, 1990, the Technical Development Bureau of China National Coal Mine Corporation organized and passed the letter of research on the results of research on the 6.0m interval of rigid wellbore equipment. The research was jointly completed by China University of Mining and the Yanzhou Mining Bureau, 37 Engineering Department. In the annual design capacity of 4Mt Dongtan mine main shaft wellbore equipment construction, Yanzhou Bureau 37 Engineering put forward the cannel beam spacing increased from 4.0m to 6.0m proposal.After Yanzhou Coal Mining Design Institute approved
