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 m
3/h to 0.6 m
3/h, achieving a 75% reduction. The residual seepage volume is significantly lower than the treatment target threshold of 1.0 m
3/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.
