摘要
开展受承压水威胁煤层底板岩层成份、微结构和水稳性研究,获取其阻水性能,是煤矿防治水的重要工作.基于岱庄煤矿受高承压水威胁的下组16煤层首采11605工作面煤层底板岩性阻水性实验数据,得到了岱庄煤矿下组16煤层底板不同岩层的组成成份、微结构和水稳性特征,为岱庄煤矿承压水防治提供了科学的计算参数.
It is an important foundation work for water hazard prevention in the coal mine to obtain water resistance of the seam floor by studying rock composition,microstructure and water stability.Based on the experimental data of water resistance of the seam floor of 11605 working face in the 16 th under-group coal seams,which were threatened by confined water,we summarized the strata feature of composition,microstructure and water stability to provide scientific parameters for confined water hazard prevention in DaiZhuang coal mine.
