Gubei Ore Mining Surface Movement Observation Station Design

Rock strata and surface movement caused by mining process is very complex, it is the result of many integrated geological and mining factors. At present the main method is field observations, by observing gain a huge mass of data, then comprehensive analysis of these data, to find out the influence law of various factors on the movement, at last to apply this rule to practice to solve the problem of mining subsidence, make it further improve and deepen. In order to field observations, before the conducted in mining, must set the subsidence observation on the selected place. In the process of mining, according to the need regular observation the charge of the space location and the relative position of the measuring point, to determine the location and relative movement between the points, so to master the law of mining subsidence. Surface movement observations station layout elaborated the personal point of view, in order to provide help for surface movement observation station layout.Analysis station design methods, this paper made a detailed analysis of the method. At the same time to Gu north mine north (6-2) on the mining area and north of12326face a (6-2) on the surface movement deformation monitoring of mining12126working face as the background, the paper introduces the design of the observation station in mining subsidence monitoring system and implement. The paper introduces the design process of the station in detail, and use of north mining working face in12326and12126the actual geological and mine data, to set up stations in face above the surface. Using GPS static positioning technology to observe the control point of connection, introduced the D requirements of the GPS network observation and data processing, gain the location of the observatory control point information. Before the ground has yet to produce mobile, for the first time to establish the observation data and the base of the observatory is using GPS-RTK positioning technology, observation in the process of using the technology of GPS static relative positioning, GPS CORS technology, digital leveling technology and other advanced technology; On data processing, in addition to the conventional least square estimation theory, also used the differential resistance estimation theory, advanced data processing methods; On using the data processing software, besides using the GPS baseline vector calculating software, other all use on its own research and development of the "mining subsidence integrated data processing and analyzing system software package", in order to observatory’s adjustment calculation.Above of working face through long-term observation of surface movement observation station, data acquisition, processing analysis, has obtained the certain data, study of existing data analysis, grasps the work for mine safety production guarantee, also for the future similar cases of surface movement deformation provide valuable experience.
