Engineering of and Design Research on Curtain Water Blocking Project in Qingzhou Dianzi Iron Mine

Abstract:

The geological conditions are complicated and groundwater is rich under Qingzhou Dianzi Iron Mine which is planned to be developed. That seriously affects the mining of iron ore. The border of water block curtain, water block depth, water block materials were determined after scientific analyses on hydrology and geology condition and some geophysical survey. The drilling techniques and grouting procedures were optimized. The problems occurred during construction were researched and resolved. The task of water block within mine area was successfully completed.
