摘　　要：随着煤炭资源的大面积开采,神东矿区地表沉陷范围逐年增大,给周边生态环境和居民生活带来严重困扰。为了平衡煤炭开采和生态环境保护,基于GPS采集技术,优选具有代表性的布尔台煤矿22207工作面、哈拉沟煤矿22521工作面、上湾煤矿12401工作面和锦界煤矿31408工作面进行地表变形监测,对观测结果进行曲线分析和参数确定。结果表明:神东矿区南部和北部区域采煤工作面地表下沉量较小,矿区中部区域地表下沉量较大;最大下沉点附近地表沉降幅度较稳定,而在拐点附近地表沉降幅度变化大;地表下沉曲线的拐点和最大下沉点附近地层水平方向变形强烈;矿区工作面平均采深越大,起动距、超前影响距和主要影响半径就大。研究结果对神东矿区后续地下采煤和地表沉陷控制平衡发展,提供一定的数据支撑和理论依据。With the large area mining of coal resources,the ground surface subsidence in Shendong mining area has been increasing year by year,causing serious problems to the surrounding ecological environment and residents.In order to balance coal mining and ecological environment protection,based on GPS acquisition technology,this paper selected representative working faces including Buertai Coal Mine 22207 working face,Halagou Coal Mine 22521 working face,Shangwan Coal Mine 12401 working face and Jinjie Coal Mine 31408 working face for ground surface deformation monitoring,and carried out curve analysis and parameter determination of the observation results.The results show that the ground surface subsidence of coal mining faces in the southern and northern areas of the Shendong mining area is small,while that of the central area of the mining area is large;the ground surface subsidence amplitude near the maximum subsidence point is relatively stable,while the ground surface subsidence amplitude varies greatly near the inflection point;the horizontal deformation of the strata near the inflection point and the maximum subsidence point of the surface subsidence curve is strong;the larger the average mining depth of the working face,the larger the starting distance,the advance influencing distance and the main influencing radius.The results provide some data support and theoretical basis for the subsequent balanced development of underground coal mining and ground surface subsidence control in Shendong mine area.
