Pan Yi Dong Mine1242(1) Working Surface’s Analysis And Evaluation Of Mining Subsidence Damage

Mining Subsidence damage analysis and evaluation of mining subsidence is one of the main research topic,in view of China’s "three under" tremendous pressure the amount of coal mining subsidence is expected to do the work and take advantage of accurate and reliable results to guide practice exploitation of mining subsidence had to shut an important role. This urgently requires people to carry out mining subsidence damage analysis and evaluation research.This paper combines Pan Yidong1242(1) Face Surface Movement Deformation Analysis Project,introduced the implementation process of field observation data observation programs. Monitoring of control points and control points measured, connect the measurement,and comprehensive daily observation and observation. Using static GPS measurements,GPS-RTK,Precision Level elevation measurement,adjustment of observational data.According to Pan Yidong stations measured data mining analysis,combined with the geological and mining conditions and mining subsidence principle,calculate subsidence caused by the creation of various contours based on prediction:sunken contours,contours sink,tilt contour, contour curvature, horizontal movement of the contour,horizontal deformation contours. Which involves the pilot area topographic map,mining and excavation plan, movement and deformation prediction map,use the expected ground movement and deformation information under the control diagram and related software Inoue, generate three-dimensional study area mining subsidence virtual reality model and two-dimensional model,Base material resistance to deformation and subsidence prediction results,use the map statistical functions,statistical inquiry feature of subsidence area,super deformed inquiry,in order to evaluate the impact of mining subsidence on surface buildings. Ground subsidence achieve dynamic monitoring and management,in order to achieve the goal of Subsidence damage evaluation.
