According to the hydrogeological complex types of non-coal mines,combined with the actual engineering application of mine prospecting,this paper analyzes the feasibility of water exploration and drainage design,construction and grouting treatment of non-coal mines with complex hydrogeological conditions in large cross-section roadway,which provides a reference for the future hydrogeological complex mine water disaster treatment.Water disaster control is an important means to realize safety production in mines,and hydrologic complex mines are the key point of management and control in existing underground mines.This paper describes the design of water exploration and drainage under a large section of about 5m,under the condition of poor stability of surrounding rock,the grouting construction is carried out,and the design of grouting pressure and the whole process management of the early,middle and late stages of grouting are explained,the actual engineering parameters,design parameters and pressure water test are introduced,which provides a good reference value and application prospect for water disaster prevention and control in similar mines.
