摘　　要：安居煤矿现状条件下,仅存在工业场地压占耕地的问题。通过野外调查和室内预测分析认为,全矿井开采完毕、地表沉陷稳定后,预测地表最大下沉值为2 506 mm,对东部南阳湖影响最大,对村庄、G105、S251公路和兖新铁路的影响不大;开采过程中将破坏3上煤层顶底板砂岩含水层,对下伏三灰含水层也将产生较严重的影响;受地面塌陷影响的耕地面积将达到58.43 km2,其中89.22%的耕地下沉值小于0.5 m,受塌陷影响轻微。建议矿山采用土地平整和矸石充填工程治理受塌陷影响的耕地,闭坑后进行土地复垦绿化工程,并建立矿山地质环境监测体系。Under the status quo of the Anju coalmine, only one issue is existed, thus the coalmine surface installations farmland occupy- ing. Through field investigation and indoor prediction analysis have considered that after coalmine exploited and surface subsidence stabilized, predicted surface maximum subsidence is 2 506 mm; and impacting largely on the Nanyang Lake bottom in the east, less impacting on villages, GI05, $251 highways and Xinxiang-Yanzhou railway. During the mining will do harm to coal 3U roof and floor sandstone aquifers, also seriously impact underlying third limestone aquifer. Totally 58.43 km2 of farmland will be impacted by surface subsidence, in which, subsidence of 89.22 % farmland will be less than 0.5 m, thus slightly impacted. It is suggested to govern impacted farmland through land leveling and gangue filling, after coalmine closed can carry out land rehabilitation and landscape engineering, establish mine geological environment monitoring system.
