以与318工作面北侧地质和采矿条件均类似的工作面开采前所在泗河东河堤布设的19个沉降监测点数据为背景,对比分析了开采317工作面时泗河东河堤19个监测点不同时间段的差异沉降变化特征。研究结果可为318工作面3煤层综放开采前泗河东河堤加固与防治提供重要参考依据。
Based on the data of 19 settlement monitoring points laid in the east bank of the Si River where the mining face was similar to the geological and mining conditions on the north side of the 318 face, the monitoring points of the east embankment of Si River at 19 monitoring points Different subsidence characteristics of different time periods. The results can provide important reference for the reinforcement and prevention of Si River east embankment before fully mechanized caving in No.3 Coal Seam.
