徐州是一个开采百年以上的老煤矿区,是江苏省主要煤炭生产基地。从20世纪70年代开始,煤炭开采造成的地表下沉、塌陷使耕地逐年减少,农田水利设施及公共基础设施遭到不同程度破坏。到2006年6月全市采煤塌陷地己超过20多万亩,其中绝产面积约11万亩,有27万多农民完全失去了土地。人地矛盾加剧,土地资源对经济社会发展的制约瓶颈凸显,采煤塌陷地复垦已刻不容缓。 Xuzhou is a mining old coal mining area of ​​more than a century, is the main coal production base in Jiangsu Province. Since the 1970s, surface subsidence and collapse caused by coal mining have reduced farmland year by year, and farmland water conservancy facilities and public infrastructures have been destroyed to varying degrees. By June 2006, the coal mining subsidence area of ​​the city had exceeded 200,000 mu, of which the abolished area was about 110,000 mu and more than 270,000 peasants had completely lost their land. The contradiction between people and land is exacerbated. The bottleneck of restricting economic and social development of land resources is highlighted. It is urgent to reclaim coal mining subsidence.
