In order to realize its modern task, mine measurement must be making full use of modern surveying and mapping instruments and techniques, put the advanced modern technology with mine surveying the actual work, specific characteristics, and the bination of broaden the living space mine survey and business scope, promote the reform and development of mine survey, adapt to the market economy system and mining system reform needs. Electronic tachometer, space information technology, the inertial measurement system and other modern surveying and mapping instruments have been in mine survey technology is used to further development and are constantly. This paper to modern surveying and mapping instruments of the development of the technology and its application in mine. Electronic tachometer and its application in mine survey: Electronic tachometer as the most widely used surveying and mapping instruments, is electronic technology and optical technology development of the bination of the photoelectric measuring instrument, is also set range finder, electronic advantages in a wide range of instruments, application prospects, the intelligent electronic tachometer is currently the biggest selling surveying and mapping instruments, is also the main future development direction. Intelligent electronic tachometer is with light, electricity and magism, machine of the latest scientific achievements, set the location, measuring Angle for the integration of advanced instrument. The international advanced electronic tachometer are on a memory card, internal memory or electronic hand book way, way of double record data transmission munication function, can receive external puter instruction by the puter input data, also can to outside the puter output data. The international advanced electronic tachometer have Japanese SOKKIA POWERSET series production of electronic tachometer and SET5F, SET6F, SET5W electronic tachometer, Swiss produces the TCA100 and TCA1800 electronic tachometer, Japan NIKON DTMA series of electronic tachometer, etc. Our country has just south of the surveying and mapping instruments pany production NTS200 series electronic tachometer. Electronic tachometer has set up a file in the engineering survey, mine surveying, cadastral etc a wide range of applications, its development and application is in rapid developing. Electronic tachometer because and has the advantages of transit and range finder, and provide measurement results in digital form, its simple operation, stable performance, data can be through the electronic hand book and the puter to carry on the advantages of munication in the mine in the measurement of a wide range of applications. The ground control survey, topographic, engineering surveying all available is, contact measurement, the measurement work can also be used inunderground i To as a representative of the intelligent, digital instrument is minesurveying instrument one of the development direction in the future. Based on theelectronic tachometer and the modern puter technology can establish a mine 3 d data to be automatic collection, transmission,processing of mine surveying dataprocessing system, instead of traditional hand book records, manual entry, detailed calculation of repetitive work. In addition, electronic tachometer in mine surfacemovement monitoring, land reclamation project implementation, mine construction aspects also have been applied, each big o
