Research On Iron Ore Baiyun East Slope Forecast System

In recent years, national economy's swift development, the humanity in such as geological project fields of activity and so on water and electricity, strip mining, energy and building presented more and more Gao Dou the side slope, but these high steep side slopes often become the restriction economic development and the safety in production success's or failure's important attribute. Therefore, has the extremely important theory and the practical significance to the side slope jitter's research. This article will carry on the monitor, the forecast and the landslide forecast research in view of the strip mine side slope's future trend of development. Finally draws support in the coordination - branch theory carries on the forecast to the side slope destruction time. Achieves finally to the side slope carries on the jitter forecast the goal, gave the general engineers and technicians to provide one kind of research, the solution actual problem new mentality, the new method more importantly.The present paper first synthesizes the existing monitor instrument and the monitoring method, proposes the reasonable strip mine side slope monitor plan. Adopts the advanced GPS whole world satellite positioning technology all around to build 5-7 control points now in the strip mine side slope, in view of the fact that the GPS localization technology is big in altitude figure's precision flaw and the strip mine side slope hypsography all around, here we have not used the elevation fitting the principle, but uses the principle which to the control point altitude figure the third-class standard association measured, uses the precise entire station meter in various control points to carry on the displacement data finally to the strip mine side slope the monitor. Makes the generalized analysis in the forecast aspect to the former prediction theory, then takes a misalignment diffusion dynamic system this angle from the side slope to consider the side slope the stability. How in the article discussed to utilize the restructuring phase space and the grey theory correctly effectively carries on the forecast to the side slope development, then extracted system's some characteristic quantity like Lyapunov index. May establish the displacement forecast model using this index's invariability, like this may make the forecast to the side slope future displacement change. In the article has carried on the examination through the massive examples to the displacement forecast model, summarizes the restructuring phase space and the grey theory forecast that the respective forecast rule, the final operation proof forecasting result is satisfying. Finally draws support in the coordination - - branch model calculates the time which the side slope possibly destroys.The present paper through used US Microsoft Corporation famous application procedure development kit - Visual C++ 6.0 and SQL Server2000 has established the movement in operating system's and so on under the Windows 98/2000/XP 32 application procedures; Specially uses the higher order language in the data management aspect to the SQL2000 database exterior execution method, causes the scene software operators not to need the understanding database the knowledge then to be possible with ease to carry on the data the management, increased software's feasibility; The strip mine side slope's displacement forecast that the forecast process calculates completes automatically completely based on the computer, generally the technical personnel want to do merely input some parameters which the measuring point the space coordinates data and the forecast need, through the selection menu option and the one-shot button, can realize to the Baiyunebo iron ore east the ore side slope jitter predict that thus causes the general technical personnel to liberate from the arduous computation, places in the concrete fundamental research the energy.
