济宁市采煤塌陷地状况与治理途径研究

Study on the Status of Coal Mining Subsidence and Its Control Measures in Jining City

为了更合理、高效地利用煤炭资源,保护采煤塌陷地的生态环境,采用济宁市1987年TM遥感影像和2002年的ETM+遥感影像和近年来的统计资料,对部分采煤塌陷地进行现状分析,并由煤炭产量预测塌陷面积变化的大致趋势。预测结果表明,到2010年济宁市采煤塌陷面积将新增116.85 km2,到2015年新增采煤塌陷面积将达到151.88 km2,最终将形成兖州、济东两大煤田塌陷区。采煤塌陷面积的大量增加,给当地工农业生产、社会经济和生态环境等带来一系列问题,鉴于此,提出了采煤塌陷地生态复垦的综合治理途径。

In order to use coal resources more reasonably and efficiently and protect the ecological environment of coal mining subsidence, this paper uses the 1987 TM and 2002 ETM＋ remote sensing images in J ining City, the statistics of Jining City in recent years of making a status quo analysis of the part of the mining subsidence in Jining City, and forecasts the change trend in general on the basis of coal produetion. Tt-e results show that mining subsidence area in Jining City will increase 116. 839 5 km^2 by 2010 and the new mining subsidence area will reach to 151.88 km^2 by 2015 and eventually will form a large subsidence area in Yanzhou-Jidong two major coalfields. The great increases in coal mining subsidence area will result in the deterioration of the ecological environment, and bring about a series of problems to the local industrial and agricultural production as well as social, economic and ecological environments. So, in this paper, we put forward a number of scientific, rational and comprehensive control measures of coal mining subsidence.
