【摘要】 在调查分析潘集矿区按"规程"留设足够高防水煤岩柱和数个综采工作面出水实际资料的基础上,首次提出高承压松散含水层水体下存在"下渗带"的概念,并分析了"下渗带"的形成机理、影响因素;将"下渗带"与导水裂隙带结合,分析了高承压松散含水层下,按"规程"留设足够防水煤岩柱的综采工作面顶板充水的原因。更多还原

【Abstract】 Base on the investigation and analysis on the sufficient height water prevention coal and rock pillars left according to the "mine safety regulations" and the actual water inrush information of the several fully mechanized coal faces in Panji Mining Area,firstly the paper provided the "low penetration zone" conception existed in the high pressurized bearing loose aquifer and analyzed the formation mechanism and influence factors of the "low penetration zone".In combination with the "low penetration zone" and water conducted crack zone,the paper analyzed the roof water filling cause of the fully mechanized coal mining face with sufficient water prevention coal and rock pillars left according to the "mine safety regulations" under the high pressurized loose aquifer.更多还原
