摘要
Abstract
The lower aquifer of Quaternary in the shallow coal seam of Gaozhuang Coal Industry is the main direct water filling source,while the thick loose layer of Quaternary in the 3lower302 working face directly covers the bedrock,which poses a certain risk of water inrush and sand collapse accidents during the mining process.In order to avoid the risk of accidents,the feasibility study of setting up safety coal and rock pillars for shallow coal seam mining focuses on studying failure height of overlying rock and structural characteristics of bedrock,analyzing and studying the sedimentary combination structure characteristics and water richness of bedrock overlying loose strata.Through methods such as on-site investigation and research above and below the mine,comprehensive analysis of data and so on,a detailed analysis and research are conducted on aspects of spatial distribution characteristics,lithology,water richness and others of the Quaternary strata in the 3lower302 working face.This provides important technical basis for the safety level of setting up waterproof coal and rock pillars in coal seam mining and eliminates the risk of water inrush and sand collapse accidents in this working face.关键词
