“三下”采煤的实践中,常需查明移动盆地内某点的移动和变形(或沿某一方向的变形),用传统的计算方法较为复杂且不直观,现场技术人员难以掌握,特别是在无计算机的情况下更是如此。本文在概率积分法基本原理的基础上,导出比较简单且直观的计算方法,借助于草图和计算表,可以很方便地进行计算。此外,根
In the practice of “three times” coal mining, it is often necessary to find out the movement and deformation (or the deformation along a certain direction) of a point in the moving basin. It is difficult and difficult for the technicians in the field to grasp it with the traditional calculation methods. This is especially true in the absence of computers. Based on the basic principle of probability integration method, this paper derives a relatively simple and intuitive calculation method. With the aid of sketches and calculation tables, it can be easily calculated. In addition, roots
