Dynamic Monitoring of Gob Floor Water Hazard with Rectangular“Bipolar-Bipolar”Resistivity Method
ZHANG Zhenyong
Abstract：In order to Prove uP the floor water hazard in the gob,a new D. C. electrical method named as“biPolar-biPolar”resistivity method was used for the detection. This method solved the Problem that the electricity can’t be directly suPPlied in the gob,and through the Pre-buried electrodes and cable in the roadway,the dynamic monitoring of the floor water hazard in the gob of the working face was thus realized. In the asPect of data Processing and interPretation,the use of the resistivity tomograPhy inversion calculation imProved the interPretation accuracy. The simulation exPeriment and Practical aPPlication Proved its validity and suPeriority. This method can be used to Predict the occurrence time and Place of the Possible water inrush in the mining Process of the working face so as to do well the water Prevention and control work in a Planned,steP by steP and targeted way.
