摘　　要：高庄煤业浅部煤层第四系下部含水层是主要直接充水源,而3_(下)302工作面第四系厚松散层直接上覆于基岩,在开采过程中具有一定的突水溃砂事故的风险。为了避免事故风险,对于浅部煤层开采安全煤岩柱留设的可行性研究,重点研究覆岩破坏高度及基岩结构特征,分析研究基岩上覆松散地层的沉积组合结构特征及富水性。通过井上下现场调研、资料综合分析等方式,对3_(下)302工作面从第四系地层空间分布特征、岩性、富水性等方面进行了详细的分析研究,对煤层开采的防水煤岩柱留设安全程度提供了重要的技术依据,排除了该工作面突水溃砂事故风险。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 3_(lower)302 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 3_(lower)302 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.
