厚松散层薄基岩下综放开采对河堤沉降影响研究

Influence of Fully Mechanized Caving Mining on Riverbank Subsidence under Thick Alluvium and Thin Bedrock

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。

Study the working face which is on the north of the 318 working face, the 19 in-situ monitoring subsidence points were arranged along the Sihe river east embankment as the background, differential subsidence characteristics is compared in different periods when the mining of 317 working face was to close the Sihe river east embankment. The results provide an important reference for prevention and cure the Sihe river east embankment before the 318 working face mining coal seam.
