| 摘 要： | 根据铜录山地区历年降雨量对矿坑涌水量的影响情况,运用样条插值函数对建帷幕前降雨量与排水量的关系进行了计算、研究与分析,得出了它们在各降雨区间上的函数关系;提出了一种能较好地计算堵水率,评价帷幕注浆效果的方法。利用该法对铜录山矿帷幕注浆堵水率进行计算,表明该法是一种行之有效的方法。

| Abstract: | on the basis of influence of rainfall over the years on underground water flow in Tonglushan mine field the relationship between rainfall and drainage rate prior to curtain grouting was studied by means of spline interpolation on the computer. Function relation between rainfall and drainage rate in various rainfall periods was found. A better method for calculation of water cut-off rate and evaluation of curtain grout effect was proposed. The cut-off rate of curtain grout in Tonglushan mine was calculated using this method. The results proved it to be effective. |
