Study On The Dynamic Monitoring System Of The Destroy Of The Bed Plate And The Water Of The Bed Plate

Lagging water-inrush of working face threatens the safe of the coalmine. The thesis exploited the dynamic system of monitoring the water of bed plate and apical plate applying the technique of high density electrical resistivity. The system can dynamicly monitor the working face and the destroy depth of bed plate of goaf and the moving course of water of bed plate. And the thesis can ahead monitor, predict and harnessing the water of bed plate in working face and goaf.The system is made up of the system of collecting the data of electrical resistivity, the system of receiving and transforming the data and the system of processing data. The system of collecting the data of electrical resistivity uses WGMD-2 high density system. The system of receiving and transforming the data uses the system of BTW2000 data communication. The system of processing data uses the program of electrical resistivity inversion of RES2DINV and RES3DINV.We succeed to monitor the whole course of water-inrush of 51302 working face in liangzhuang coalmine with applying the system and draw many invalubleners geologic conclusion.
