摘要
为解决已有不规则工作面沉陷预计方法的不足,对不规则工作面积分区间的三角剖分方法进行了研究,推导了不规则工作面二重积分过程中各三角形积分域上下限的确定公式;顾及到不同三角形形状及坐标系的相互转换,设计了不规则工作面的三角剖分算法;基于该算法,利用MATLAB软件开发了预计程序,该程序可对缓倾斜任意工作面开采进行地表沉陷预计,可对预测结果进行直接处理而不必采用第三方辅助软件,并且实现了预测数据的实时可视化。
In order to solve the problems existing in subsidence prediction for irregular working surface, through the research on the triangulation method in irregular working face, the upper and lower bounds of each integral region for double integrals are derived. Considering the different shapes of the triangle and the conversion between different coordinate systems, a triangulation algorithm for irregular working face is designed. A subsidence prediction program is developed based on MATLAB software and the triangulation algorithm. The program is not only applicable to the surface subsidence prediction of gently inclined working surface under different shapes, but also used to process the results directly without needing to use the third party auxiliary software, which can realize the real time visualization of the subsidence prediction data.
