山东济宁市煤炭资源丰富,分布面积3920平方公里,占全市国土面积的37．4％。近年来,随着各县区地方煤矿的无序建设,地下煤炭资源被疯狂式开采。济宁煤炭业的大力推进带动了矿区周边农村经济的发展,然而,煤矿开采的最大弊端在于产生大量的煤炭塌陷区,使大面积的耕地沦为湖泊和沼泽。目前,全市已有10万余亩煤矿塌陷地,失地农村20余万人,随着 Jining City, Shandong Province, rich in coal resources, the distribution area of ​​3920 square kilometers, accounting for 37.4% of the city’s land area. In recent years, with the disorderly construction of local coal mines in counties and districts, underground coal resources have been wildly mined. However, the biggest drawback of coal mining is that a large amount of coal subsidence area is created, which makes the large-scale cultivated land become lakes and marshes. At present, the city has 100,000 mu of coal mines collapsed and more than 200,000 people have lost their land in the countryside
