Comprehensive detection of hydrogeology conditions in mines and research on water prevention and control technology
To explore the characteristics of mine hydrogeology conditions,provide important reference basis for the water prevention and control technology scheme,taking the southwest Yuwang Coal Mine as the research object,for the existing problem of high mine water inflow,the hydrogeological conditions were comprehensively detected.Five detection modes,including isotope test,ground transient elec-tromagnetic method,underground advanced drilling,horizontal ground temperature monitoring and underground actual drilling,were spe-cifically applied.After integrating the data information of the five detection modes,the mine water supply path was clarified.Based on the comprehensive detection results,the combination of dewatering and pressure reduction and grouting waterproof operation was deter-mined to carry out water prevention and control operation,and the key points of water prevention and control operation were described.The results of the analysis of the application effect of water prevention and control operation showed that after the application of the water pre-vention and control technology scheme,the water inflow of the mine working face was significantly reduced,proving that the comprehensive hydrogeology exploration and water prevention and control technology scheme for the target mine has good application value.
