绳索取心钻进技术在大安山矿区的应用

Application of borehole wire line coring technology in Daanshan mining area

以大安山矿区井下绳索取心钻进工程为例,结合常规绳索取心钻进工艺方法和钻进参数,分析在井下巷道勘探施工中绳索取心钻进的参数选取,并对绳索取心钻进技术在巷道施工中应用作出经济评价,为绳索取心钻进技术在巷道勘探中的应用推广提供了参考。

The parameter choice for wire-line core drilling in the underground roadway exploration is analyzed and the economic e- valuation is made on the wire-line core drilling in the underground tunnel exploration, to lay the foundation of the wire-line core drilling in underground tunnel popularization., taking the apply wire-line core drilling in underground tunnel exploration to Daan- shan mining area as example and combined with conventional wire line core drilling method and parameters.
