Development of a New Mining Intrinsically Safe DC Electrical Prospecting Apparatus

The DC electrical prospecting apparatus plays an important role in the prevention of water disasters in coal, but most of traditional instruments of this kind for mining use 51 series MCU as the core chips, which has the defects such as high power consumption, small storage capacity, inconvenient operation and difficult to carry with, all of them restrict the applications of the DC electrical prospecting apparatus. This paper starts from the principle of mining DC electrical prospecting instrument, and designs a new type of this kind of device by the modular method, the system includes system module, transmitter module, receiver module, storage module, communication module and ect.. .And at the same time, it also affords the electrical performance of the system. Finally, by doing the comparison test with the traditional instruments, it proves of the advantages of the new electrical instrument, such as high precision, low cost, low power consumption, much more storage capacity, convenient communication, friendly interface and so on.
