超深矿井围岩裂隙渗水综合治理研究与实践:以首钢马兰庄铁矿1#主溜井为例

    Research and practice on the comprehensive treatment of water seepage through fractures in surrounding rock of ultra-deep mine shafts: a case study of Shougang Malanzhuang Iron Mine’s No. 1 Main Ore Pass

    • 摘要: 针对超深溜井渗水威胁矿山安全生产的问题,本文以首钢马兰庄铁矿1#主溜井−488 m水平渗水治理工程为例,提出“查、疏、堵、截、排、引、固、验”一体化协同治理技术。通过融合特殊布孔形式、帷幕注浆、导水孔引流、地球物理探测验证及多类型材料配比优化等工艺,结合全过程质量控制体系,实现了超深溜井渗水量由2.4 m3/h降至0.6 m3/h,降幅达到了75%。溜井残余渗水量显著低于治理目标阈值1.0 m3/h和行业规范标准的要求。因此,工程实践表明,该技术体系对超深部矿井渗水治理具有显著推广价值。

       

      Abstract: In response to the threat of water seepage in deep ore passes to mine safety production, this paper takes the water seepage control project at the -488 m level of Shougang Malanzhuang Iron Mine’s No.1 Main Ore Pass as an example, proposing an integrated collaborative management technology centered on “investigation, drainage, blocking, interception, discharge, diversion, consolidation, and verification”. By integrating processes such as special borehole layouts, curtain grouting, drainage hole diversion, geophysical detection verification, and optimization of multi-type material ratios, along with a whole-process quality control system, the water seepage volume in the deep ore pass is reduced from 2.4 m3/h to 0.6 m3/h, achieving a 75% reduction. The residual seepage volume is significantly lower than the treatment target threshold of 1.0 m3/h and the requirements of industry standards. This engineering practice demonstrates that the technical system has significant promotional value for water seepage control in deep mine shafts.
