| 摘 要： | 莱芜市煤炭和铁矿资源丰富,开采历史悠久,矿山排水量较大。煤矿矿坑水中SO42-、总硬度、矿化度、F-等组分较高,对地下水水化学场构成影响,矿区附近SO42-含量大于300 mg/L的孔隙水分布面积9.98 km2。铁矿排水具有高强度、大降深、强烈疏干的特征,导致矿山背斜东翼已形成水位降落漏斗,其中水位标高120 m的漏斗面积达27.5 km2,由于矿坑排水加之水源开采,1973年以来赵庄、孟家庄、西泉河地段共发生岩溶塌陷220处,塌陷总面积8 880 m2。

| Abstract: | Coal and iron resources are very rich in Laiwu city.The mining history is very long,and mine discharge amount is great.Compositions as SO2-4,total hardness,degree mineralization and F-in coal mine water are very high,which will effect the chemical field of underground water.Distribution square of crack water which SO2-4 content is above 300mg/L is 9.98km2.Iron deposit discharge has the characteristics of high intensity,large deepness and strong unwatering.Funnels have been formed in east part of mine anticline.Among them,funnel square with the water level over 120m are 27.5km2. Due to coal mine discharge and water source exploitation,220 karst collapse have happened in Zhaozhuang,Mengjiazhuang and Xiquanhe sections from 1973,and the total collapse squares are 8800m2. |
