摘　　要：介绍寿王坟铜矿上部采空区内存窿矿石地下溶浸注浆防渗试验结果和现场施工效果。试验采场注浆孔总长798 4m ,注浆量 11 3 7L·m- 1 ,注浆压力 1 5～ 2 0MPa,注浆成本 1 0 6元·t- 1 矿 ,注浆后矿体吸水率 0 2 5 9L·min- 1 ·m- 1 ·m- 1H2 O ,渗透系数 0 0 3 0 1m·d- 1 。注浆防渗技术用于解决地下溶浸浸出液渗漏问题是可行的。The results and effects of experiment and practice in test stope on grout curtain and penetration resistance technology for solution seepage prevention of the residue ore in situ leaching in Shouwangfen Copper Mine are described. In the operation of test stope, the total length of penetration holes is 798.4m, the penetration volume is 11.37L·m -1 hole, and the penetration pressure is 1.5～2.0MPa and the cost is 1.06$·t -1 ore. The water adsorption rate and seepage coefficient of the penetrated ore body are 0.259L·min -1 ·m -1 ·m -1 H 2O and 0 0301m·d -1 respectively. The grout curtain and penetration resistance technology is feasible to prevent the solution seepage of the residue ore in situ leaching in Shouwangfen Copper Mine.
