The Imager Technology Of Concurrent Electrical Meter

The mine water disaster is the threaten of coalmine safe-production,a planty of research have been carried out in the electrical field at present time both home and abroad.Although these research get many achievement,there are many problems in their efficiency,accuracy and pertinence.This paper bases on the theory of electrical imaging technology,the main reasearch is about how to detect the water disaster during the coal face production and roadway excavation by using concurrent electrical acquisition technology to supply effective technology indemnification serve for coalmine safe production.Paper give many survelliance systems acconding to difference kinds of mine water disaster by incorporating the concurrent data:surveillance bore can be designed on the upper plate of coal face to monitor the three zone;electrical prospecting system can be put in the roadway and cut hole;the Bipole-dipole can explore the water disaster in bottem plate,and Dipole-dipole also can protect the tectonic in the coal face;the U mode of survelliance system can locate the anomalous body forward the roadway. Paper has made a further research about the processing of concurrent electrical data and finished the imager technology,it is mainly include conventional processing method,high resolution and 3D inversion technology,the resistivity tomography has also been introduced at last.Paper use conventional processing method for primary analyses;use the high resolution method to carry out multipoint convergence for the anomalous body forward the roadway and use the 3D inversion for locate the distribute of anomalous body in three dimension.By analysing the numerical simulation and physical experiment,the survllience system and technology get application in the engneering and reach the goal.The concurrent electrical imaging technology has high detection effieiency and locate abnormal body accurately,it has amplitude application value.Paper point out the technology problems during the imaging research and research direction in future.
