Abstract: The water filling factors,gushing water law and main factors affecting mine water inflow for Jinjie Mine are analyzed based on a large number of production data.The research indicates that Jinjie Mine's main water filling channel is water flowing fractured zone formed by coal seam mining,main direct water filling source is from the weathering bedrock pore fissure water-confined aquifer of middle jurassic Zhiluo group, secondly is from the phreatic aquifer of Quaternary upper Pleistocene Series Sarah WuSu group；working face is the main source of mine water gushing, then is from goaf. After five years of mining, water inflow has peaked,and currently shows a tendency of slow and steady decline. The main factors affecting mine water inflow are the coal production, mined-out area and thickness of overlying weathering bedrock.
