【文章內容簡介】 GPS and INSAR technology During mining survey, most mon works are involved with monitoring the earth surface deformation, especially in monitoring the mining subsidence and coast. It plays a very important roles in mine safety production. For monitoring mining subsidence, Interferometric synthetic aperture radar (InSAR) and GPS technology are very strong plementary. Firstly, GPS belongs to point positioning, and the length of base line is usually tens to hundreds of kilometers. Such lower point density cannot meet the demand for high spatial resolution monitoring of the surface deformation. InSAR data can apply continuous information off the entire region surface. The spatial resolution can reach to 20 m. Secondly, InSAR (spatially differential InSAR) is sensitive to elevation information of the earth surface owing to the radar incidence angle effect, while GPS is unsubstantial in elevation precision. Thirdly, GPS has high temporal resolution (highest can be up to 1 Hz), while InSAR data has a lower temporal resolution (more than 20 days generally, highest only can be 1 day) because of the loner revisiting period. The integration of TPS total station and GPS As a new instrument which integrate the GPS total station and GPS, Smart Station—a super total station theodolite is practicable. This instrument doesn’t need ground control points, long traverse and resection operation. We can use the total station theodolite to survey and layout only by setting up the Smart Station and use the GPS to locate the occupied station accurately. It can abtain the position information with centimeter level accuracy within very short time while the baseline is short than 50 km. The fusion of GIS and puter work In order to instruct the mine safety production efficiently, many countries are developing mine geographic information system (MGIS) and suing the advanced radio frequency identification device (RFID), puter work technology and Field Bus munication technology in this system, which solved the problem of underground operators accurate positioning and the miner work attendance check. The fusion of GIS and puter work technique provide a well guarantee to mine safety production. 4 New ideas to modern mining survey Setting up and making perfect of Web Mine GIS At present, the foremost task is to sep up the MGIS with integral and powerful functions in the mine construction. It is a management information system. We can exploit systematically, synthetically, dynamicly and roundly ground and underground natural resources by regular and high and new technology, instruments and methods. Based on it, we can set up a mine resource and environmental information system. The system applied spatial information technology is an allaround achievement by integration of 3Stechnology, Total Station and other surveying instruments and technology in the mine surveying. MGIS has been the main aspect and inevitable tendency of the development of mine surveying. It mainly studys on the collection, save, process, analysis, simulation and reappearance of mine time and space data, which has a better editing map ability and connects automatically the spatial data with the attribute data, exploits mine excellently, uses resources reasonably, analyzes and appraises environment and decides regional plan and sustainable development and so on. According to the characteristics of mine plan and construction, MGIS should mainly include many subsystems as follows: mine geology and surveying information system, mine dispatching management information system, mine production management information system, mine destructions and accidents forecast system, mining district plan and mine shaft design information system, mine district land reclaimation management information system and mine subsidence forecast system etc.
