大型矿井建井期间改绞方法研究

Study on the methods of modification of hoister of large mine during shaft construction

针对大型矿井建井工期长的技术难题,通过分析研究提出了风井井筒采用双提升系统改绞的方式。合理控制矿井建设工期,可有效缩短工程投资回收期,提高矿井经济效益。该文以石拉乌素矿井为例,简要介绍了矿井风井双提升系统改绞的优点。

aiming at the technical problems of large mine shaft construction period long, through the analysis, proposed the use of double hoisting system of mine ventilation shaft. Reasonably control the mine construction period, which can effectively reduce the engineering investment recovery period, improve the economic benefits of mine. This paper takes shilawusu mine as an example, briefly introduces the advantages of modified hoister using double hoisting system of mine air shaft.
