摘要
目前矿山存在着地面沉陷、煤矸石山、塌陷坑等诸多地质环境问题,导致矿区内土地资源和植被资源被破坏。本文结合GNSS和传统大地水准仪方法,获取吉林省长春市九台营城矿区2019年4月变形监测数据,得到该矿区在1—4月间最大沉降量与沉降速率分别为128.4 mm和15.4 mm/月,该研究变化趋势符合实际,可作为预测该矿区沉降变化的参考依据。
At present,there are many geological environment problems in the mine,such as ground subsidence,coal gangue mountain and collapse pit,which lead to the destruction of land resources and vegetation resources in the mine.Based on the Jiutai Yingcheng mining area in Changchun city,Jilin Province,the deformation monitoring data of the study area in April 2019 are acquired by combining GNSS and traditional earth level methods in this paper.The maximum settlement deformation and settlement rate for the mining area in the period from January to April are 128.4 mm and 15.4 mm/month respectively,which is consistent with the actual change trend.The results can be used as a reference for predicting the subsidence change of the mining area.
