The Data Processing Of Surface Movement Observation And Deformation Analysis

Modern continuous mining of coal resources, the initial damage of the coal and rock in mining stress under the action of deformation and failure again, what has happened to the earth’s surface features environment caused great impact. According to mouth transcribing111303mining face of KouZiDong mine project which focus on the surface movement deformation monitoring.The page mainly introduces the data processing method of surface movement observation station, process and the surface deformation lawanalyzing.First, Thepage introduces the establishment of the surface observation stationwhichestablish on thefirst miming face of111303of KouZiDong mine, data acquisition method and observation scheme. With examples explained the ground monitoring stations layout, patrol, connection survey and comprehensive observation and implementation plan, the GPS static, GPS-RTK, high precision electronic level elevation observation and other methods. Secondly, The pagethat based on the GPS network baseline calculating peace, obtained the precision of coordinate data which meet the requirements, etc. For the data processing, in addition to the conventional least square estimation theory, The page also adopted the differential resistance estimation theory to further improve the reliability of the data. It is alsoobtainedthe reliable and accuracy analysis results. Finally, according to reliable calculation result that related to the surface dynamic parameters, The page further analyzes and summarizes the mouth transcribing of the surface movement deformation law of KouZiDong mine, Provide the technical basis of science for mine exploitation, environment protection, land reclamation, etc..Studies have shown that mouth transcribing trend line for the KouZiDong mine is fullymining,while the tendency line is not a sufficient mining conditions. In the process of working face advancing, The111303mining face in the process of the whole mining deformation features largely in line with the trend line that not a sufficient mining mobile deformation law of the main sections ofhorizontal coal seam which coveredthe thick loose bed.The main section of the slope and the horizontal movement in the process of dynamic developmentis similar,with the working face advanced and the dynamic deformation extent and deformation quantity increasing, the final stable starting from the cuttingand stop line all have mobile deformation extremum (mobile deformation extremum is one negative); The main section and horizontal deformation and the deformation curvature of mobile deformation is relatively small (especially curvature deformation), The dynamic deformation are susceptible to measurement error and other factors other than mining disturbance, therefore in the process of working face advancing,the main cross section deformation characteristic curve has certain volatility. Tend to line up the mountain and the boundary, with the working face advancing, the slope deformation value is negative, the absolute value from the initial state of zero to increase gradually, after reaching the maximum under the condition, and gradually stabilized. As the working face advancing, for horizontal movement, all negative, its absolute value from zero initial state to increase gradually, after reaching the maximum under the condition, and gradually stabilized. Tendency to offline mountain border,with the working face advancing, for slope deformation values are all positive, the value from zero initial state to increase gradually, after reaching the maximum under the condition, and became smaller stable; For horizontal movement, with the working face advancing, all are positive, the value from zero initial state to increase gradually, after reaching the maximum under the condition, then became stabilize and gradually smaller.
