Computer Implementation Of Ground Subsidence With Sub-level Caving Miningin Mining Areawith Thick Alluvial Soil

Shan'xi is one of energy production base in our country. In exploitation of coal resources,We need to build up thick layers for mining top-coal caving face of the exploitation of groundmovement is expected to theoretical models in order to protect the thick layer of Shan'xiCaving stope mining ground-level structures.At the same time, it is expected to complete thedevelopment of theoretical models,and it is ensured that we need provide a scientific basis toprotect rational allocation of resources in Shaanxi coal mine development and coal miningunder buildings with the ground.This paper introduces the basic theory of mining subsidence, as well as the changes insurface mining area of three-dimensional visualization, while Comparing between theconventional theoretical models of mining subsidence and the thick layer of loose cavingsubsidence model, it focuses on two different methods of mining subsidence expected,three-dimensional performance on surface subsidence. According to theoretical model ofmining subsidence, we design the data structures and related algorithms of mining subsidenceprediction software. On the basis of mining subsidence corresponding theoretical model, it isexpected to deal with data mining subsidence. Based on the data, we established the miningsubsidence of the three-dimensional model of surface subsidence. The article focused on thethick layer of mining subsidence model and its three-dimensional model of the surface, inaccordance with this mathematical model, seted up a data structure associated with variousmodules before the software designs in order to better dealing with the design processproblems encountered.Through the DEM model established in subsidence,it calculated theperformance results of the mathematical model and produced the dynamic presentation intime by GIS. In this paper,combined with ESRI's products ArcEngine9.2 components by thedevelopment of tools,MS Visual C + +2005, it brought about the thick surface layer of mobileand Deformations software. Through the use of component-based development,geographicinformation systems technology,three-dimensional model of technology and data miningsubsidence corresponds to the mathematical calculation of the ground movement ,it wasexpected to achieve the two-dimensional and three-dimensional visualization of theperformance and complete the analysis of the corresponding functions, thereby it effectivelyprevent the exploitation of areas caused by disasters, and the rational development of miningresources in the ground to protect and reduce the losses caused by coal mining are of greatsignificance. The results showed that what this article discussed was feasible about the thickloose layer of mining subsidence prediction method.
