求人翻译一段英文摘要
Despite a principal contributor to the rapid economic growh,the mining industry in China produced a large amount of wasteland and caused water pollution and soil erosion as well as other environmental damages.In 2002,this industry generated 265.4 Mt tailings,130.4 Mt gangue and 107.8 Mt amelting slags.The degraded land associated with mining is estimated to be 3.2 Mha by the end of 2004,deteriorating the land shortage of China.Restoration of mine wasteland began in late 1970s but the restoration process was sluggish.The overall restoration rate(the ratio of reclaimed land area to the total degraded land area) OFmine wasteland was some 10-12% with a higher rate for coal mine spoils but a lower rate for metal-mined derelict land.Form 1994 to 2004,149 research papers were published about the restoration of China's mining wasteland,of which 70 were on metal-mined land and 61 on the mon-mctal-mined land.Although 37 institutions in China were involved in the restoration research,only a few remained active and productive.
参考答案:尽管煤矿产业是经济的迅猛发展的一个主要贡献者，但中国的采矿业造成了很多荒地，促使了水污染，土壤的侵蚀，和其他的环境破坏。2002年，工业产生了265.4MT的残渣废弃物，其中130.4Mt的脉石，107.8Mt的未融化的矿渣，据估计，到2004年底，由于采矿造成的土地退化的面积将达到3.2 Mha ，中国的本来就不足的土地正在恶化。早在20世纪70年代末就开始了对采矿造成的土壤恶化的改良与修复，但是进展却是相当迟缓的。那些由于采矿而遭到破坏的全部土地的修复比率（以修复的土地占全部恶化的土地的比率）煤矿采集点的土壤是10-12%较高的修复比率，但是那些被矿渣的废弃物的长久侵蚀的土壤修复的比率就低些。从1994到2004年关于如何修复中国因煤矿开采造成的土地退化的149篇论文先后发表了，其中70篇是关于那些被矿渣的废弃物的长久侵蚀的土壤修复的问题，61篇是关于mon-mctal-mined的。虽然中国的37所研究院一直投身于修复研究之中，却只有一小部分能起作用。
