留设保安煤柱可以用移动角法,也可以根据地表移动与变形的分布确定受保护边界。比较而言,后者考虑了不同建筑特征和使用条件所允许的临界变形,所以灵活得多。加之近年来地表移动盆地的研究受到相当的重视,并取得不少成果,因此,按这种方法计算也较为准确。惟其过于繁锁,在应用上受到很大限制。因而目前移动角法仍然是通常所用的主要方法并有进一步研究探讨的必要。概率积分、双曲函数、负指数函数、
The security pillars can be located by moving angle method, and the protected boundary can also be determined according to the distribution of surface movement and deformation. In comparison, the latter takes into account the critical deformations allowed by the different building characteristics and conditions of use, making it much more flexible. In addition, in recent years, the study of surface movement basin has received considerable attention and many achievements have been made. Therefore, the calculation by this method is also more accurate. However, it is too complicated and has been greatly restricted in application. Therefore, the current method of moving angle is still the main method commonly used and there is a need for further research. Probability integral, hyperbolic function, negative exponential function,
