摘　　要：隧道排水时如果在隧道附近存在矿体,流经矿体的地下水会携带一些属于矿体的溶质,而这种携带了特殊溶质的融滤水在隧道排水作用下对隧道工程以及自然环境的影响目前还没有得到充分认识,例如在隧道附近存在石膏矿时,酸性的石膏矿融滤水会腐蚀隧道结构。本文在前人的研究基础上,以经过验证的水平井捕获时间公式为线索研究了捕获时间的影响因素并运用解析解验证了捕获时间数值解的准确性。the tunnel drainage if there near the tunnel when the ore body, through the ore body of groundwater will carry some belong to the solute of orebody,and this carries on special solute melt filter water under the influence of tunnel drainage of tunnel engineering and the influence of natural environment hasn’t been fully aware that such as gypsum mine is near the tunnel, the acid mine will melt filter water corrosion tunnel structure. On the basis of previous studies, this paper studies the influencing factors of horizontal well capture time with the clue of verified capture time formula and verifies the accuracy of numerical solution of capture time with analytical solution.
