Study Of The Surgface Movement Regularity Of Multiple Mining

The ground movement Caused by the subsidence is a core content of mining subsidence, it is important for the rock and the ground surface to study its movenet regularity in time and space,which for "three under" namely:under building, railway and water have an important guiding role. According to repeat the current progress of mining and coal production requirementsAt present,according to the progress of multiple mining and the requirements of coal production,the study of multiple mining has more and more attracted people attention. In this thesis, the first mining and multiple mining with the real measured data combined with relative program, to draw each movement and deformation curve, the first mining and multiple mining of the corresponding curve and the deformation curves of the single-poin.It makes the analysis of the data more intuitive and accurate, and to study and analyze relative important parameters of ground surface movement and deformation, to find out some rules of ground surface movement of multiple mining.In this thesis, according to thick loose layer of characteristics of Huainan area,the thick loose layer and the rock layer are separated,and create model, to find the relationship under the thick soil layer, both with subsidence and the subsidence coefficient relationships.The probability integral method is very important in mining subsidence prediction in our country.This article use the prolability integral method to prediction parameters,and to get parameters with pattern search method.In the prediction and get parameters,to analyze and compare those parameters with real-measure data.With programming tool of object-oriented language VB6.0 and combining with AutoCAD2004, Strive to make analysis more simple, intuitivandautomated.Preliminary research results of this paper will have certain practical guidance values and some reference function in similar to the conditions coal production.
