The New High-density Electrical Mining Equipment Research

Due to the wide distribution of coal, coal-forming period of more occurrence state differences, extremely complex hydrogeological conditions, making the extension of coal mining and mining depth level requirements are gradually increasing. Currently exist underground conventional electrical meter resolution is not high, the low efficiency of construction, the design of new mining high-density electrical apparatus is particularly urgent. In order to compensate for the lack of downhole conventional electrical instrument, you need to automatically switch back and specify the electrodes, data acquisition parallelization significantly improve construction efficiency and data processing can be achieved at the construction site, real-time guidance and orderly conduct of mining safety this paper has more features to design a new type of high-density electrical mining instrument.Paper from the new mining projects studies the background and high-density electrical apparatus with the idea of the significance of the introduction, describe the theoretical basis of coal electrical prospecting. Analysis of the existing ground with high-density electrical instruments and their application status. Comparative analysis of the characteristics of both old and new data collection programs, proposed new mine with the overall design concept of high-density electrical apparatus; designed the core panels, data acquisition circuit, each hardware module transmitter circuit, power circuit, and built the whole circuit, the preparation of the data acquisition and processing software, the final test of the new mining high-density electrical instrument performance, the results showed that the entire hardware design and software implementation have reached the exploration indicator; reasonable hardware circuit design, software design and friendly interface, easy to operate, meet underground hydro geological exploration, coal mining efficiency and security protection.
