APPLICATION AND PROSPECT OF FINE DETECTION IN XIONG-AN NEW AREA BY ELECTRICAL METHOD

The strictest criteria for shallow electrical exploration method are up to the world level, because the criteria and measurement to develop of Xiong-An new area is laid down by China. Therefore, this paper sums up and compares two electrical methods. They are the high density resistivity method and the Multi-Channel powered electric system. Both are developed by Chinese Academy of Sciences. Both are expected to be used in the development of Xiong-An new area. The two methods can get higher horizontal resolution data than those obtained by other electric methods due to the similar configuration as the reflect seismic method. That is, laying down all of the electrodes along the survey at the same time, and collecting density data from shallow to deep through moving the transmitter. Therefore, the integral of these two electric methods can achieve fine electrical detection, and can provide high vertical resolution geophysical data for the hydrology and geology exploration task in developing Xiong-An new area.
