Study On Real Time Localization System Of Underground Mining

Earth surface positioning technique of underground mining is always a difficult problem to mineral resources management and mines environments governance. This dissertation gives a detailed discussion on the earth surface positioning technique of underground mining, by the achievements of this thesis, underground mining location can be determined quickly and geological disasters resulted from the underground mining can be avoided.Based on the previous documents, by large numbers of theoretical analysis, current situation, problems & solutions of home and abroad underground mining positioning technique are illustrated systematically. This thesis focuses on using underground sound source to positioning the gob areas. By computer modeling, theoretical calculating & deducing, realization & improvement of apparatus and test area application, using underground sound source to positioning the underground mining has been studied detailedly, the measuring methods are specified and measuring results have been achieved.Based on the geophysical prospecting theories, characteristics of sound wave propagation in mine pits and the surroundings have been analyzed theoretically and probed. On account of the test results, the apparatus has been improved to be applicable to underground mining probing. According to the characteristics of underground mining, dealing with the achieved data, studying the data processing methods, software programming and providing visualized data processing results.This thesis follows the principle of integrating theory with practice, through system data processing to evaluate the detecting methods, and then revise the measuring method to make the study more perfect and the results more practical.
