摘要
官房铅锌钨矿区团山矿段位于云南省文山州文山县内,钨矿矿体规模中等,矿区水文地质条件中等偏复杂,包含有3个含水层组.矿坑充水的主要来源是矿体顶底板围岩岩溶裂隙水中的地下水.利用大井法对矿区的涌水量进行预测,结果表明1200、1300和1400 m水平段正常涌水量分别为21587、9997和4484 m^3/d,最大涌水量分别为64761、29991和13452 m^3/d.
The Tuanshan ore block of Guanfang Pb-Zn-W orefield is located in Wenshan County of Yunnan Province, with medium tungsten orebody scale and medium-complex hydrogeological condition, including 3 aquifer formations. The main water source for pit filling is from the groundwater in the karst fractures within the roof and floor of orebody. The water inflow of the orefield is predicted with the big well method. The result shows that the normal water yields in the levels of 1200 m,1300 m and 1400 m are 21587 m^3/d, 9997 m^3/d and 4484 m^3/d, respectively, with the largest yields of 64761 m^3/d, 29991 m^3/d and 13452 m^3/d, respectively.
