摘要
论述了采矿引起的矿山土地整治中,面积测算的几种常用方法,分析了坐标法面积测算时界址点的最弱点点位中误差。根据坐标法面积计算公式,推导了面积中误差的表达式,并给出了坡面面积的计算公式。最后,根据算例计算了坐标法面积测算的精度,结果表明面积相对精度可达到1/500以上。
Several common methods for area measurement in mine land remediation are dis- cussed, and the weakest positional error of boundary points got from coordinate method is ana- lyzed. The analytic formula of area measurement error is derived based on the expression of area measurement through coordinate method, and the slope area calculation formula is also presen- ted. Finally, the precision of area measurement through coordinate method is calculated according to the example, and the results shows that the relative precision of area is up to 1/500.
