摘要：
Geological hydrology condition, structural environment, aquifuge thickness, and coal bed thickness of No. I-1 coal in Micun coal mine of Zhengzhou Coal Industry (Group) Co., Ltd., were analyzed. Possibility of water inrush from motherboard of No. I-1 coal was appraised. Major factors of induce water inrush were analyzed. Furthermore, danger area of water inrush was divided. It was indicated that safe mining on confined water at thin coal bed can be carried on, after corresponding water prevent layout. (C) 2012 Published by Elsevier Ltd.
