C#与Matlab在任意工作面沉陷预计中的应用

分析了任意形状工作面提出的开采沉陷预计方法,以概率积分法为基础,探讨了任意形状煤层预测模型,采用了对工作面坐标数据进行数值拟合和利用面积积分方法对预测模型进行预计的方法。利用C#面向对象技术和Matlab的交互式程序设计和图形显示分析功能,给出了对任意形状工作面任意方向线和单点或网格点的下沉,倾斜,曲率,水平移动,水平变形等的预计及其结果的可视化输出。能够实现曲线图,等值线图,三维图的绘制,并通过调用Mat-lab能把预测值与实测值显示对比分析。

Application of C Sharp and Matlab in Subsidence Prediction of Working Face with Arbitrary Shape

After analysis of arbitrary shape working face, mining subsidence prediction method was proposed. Based on probability integral method, arbitrary shape seam prediction model was studied, using working face co- ordinate data for numerical fitting and area integration method for model prediction. Using design and graphic display and analysis functions of C# object - oriented technology and Matlab interactive program, sinking of arbi- trary shape face at any direction lines and single point or grid point, tilt, curvature, horizontal movement, hori- zontal deformation etc. were predicted and the predicted results can visually display. It can perform graph, con- tour maps, three - dimensional mapping, and by using Matlab the predicted and measured values can be dis- played to do comparative analysis.
