【摘要】：开采沉陷预计是矿山开采沉陷的主要研究课题之一,做好开采沉陷预计工作并利用精确可靠的预计结果指导实践开采,对开采沉陷有着至关重要的作用。而地表移动变形参数是开采沉陷预计的基础,其取值的准确性决定了地表移动变形的预计精度。本文着重研究,如何根据地表移动观测站实测资料求取地表移动变形参数；并在参数解算的基础上,利用概率积分法预计模型进行地表移动变形预计。本文根据所述理论和方法,以Matlab7.10.0(R2010a)为开发平台,编写“开采沉陷预计与求参一体化系统”软件。本文在综合分析多种地表移动变形参数解算方法的基础上,利用模矢法(Pattern Search)解算地表移动变形参数。模矢法解决了利用任意形状工作面开采时的实测资料求取参数的问题。通过对地表移动观测站进行的预计值与实测值的对比分析求参效果,可知模矢法解算的地表移动变形参数准确、可靠。同时实现了该方法的计算机编程,提高了计算速度和效率。在详细研究概率积分法原理的基础上,本文采用Matlab7.10.0(R2010a)对开采沉陷预计进行了计算机编程。实现了地表移动盆地最大值预计和主断面上的移动变形预计,以及地表任意点的移动变形预计,并完成了主断面上五种特性曲线二维成图,地表下沉盆地与水平移动的三维可视化。经过实例对比分析,该模型的预计值与实测值吻合较好。
[Abstract]:The prediction of mining subsidence is one of the main research topics of mining subsidence. The parameters of surface movement and deformation are the basis of the prediction of mining subsidence, and the accuracy of the values determines the prediction accuracy of surface movement and deformation. This paper focuses on how to obtain the deformation parameters of the surface movement based on the measured data of the ground movement observation station, and based on the calculation of the parameters, According to the theory and method mentioned above, the software of integrated system of mining subsidence prediction and parameter seeking is compiled on the platform of Matlab 7.10.0 / R2010a. In this paper, based on the comprehensive analysis of various methods for calculating the parameters of surface movement and deformation, The mode-vector method is used to calculate the deformation parameters of the surface movement. The mode-vector method is used to solve the problem of obtaining the parameters by using the measured data of the mining face with arbitrary shape. The predicted value and the measured value of the observation station of the surface movement are obtained by means of the mode-vector method. Comparing and analyzing the effect of parameter, It is known that the parameters of surface movement and deformation calculated by modular vector method are accurate and reliable, and the computer programming of this method is realized, and the calculation speed and efficiency are improved. On the basis of studying the principle of probabilistic integration method in detail, this paper uses Matlab 7.10.0 / R2010a to program the prediction of mining subsidence, and realizes the prediction of maximum value of surface moving basin and the prediction of moving deformation on main section. And the prediction of movement and deformation at any point of the earth's surface, and the 2D mapping of five characteristic curves on the main section, the 3D visualization of the subsidence basin and the horizontal movement of the ground surface are completed. Through the comparison and analysis of examples, the predicted values of the model are in good agreement with the measured values.
