To counter the features of diversiform shapes of mining face, a method for fitting boundaries of horizontal projection of the face with quadratic curve is described in this paper. A method for processing complicated shape of the face by subsection integral also is given. The problem of partitioning the integral region of any shape of mining face is solved rationally. The formulas for calculation of the shape coefficients of the face are given, and all calculating process automatically achieved with the aid of computer. The approximate method for breaking up any shape of the face into rectangles is avoided, and the prediction accuracy of subsidence also improved. Finally, it is showed through a concrete instance that the method for processing any shape of mining face in this paper is of higher accuracy than the method currently in operation.

针对工作面形状多种多样的特点 ,本文采用二次曲线描述工作面水平投影边界 ,并且利用分段积分的方法处理更加复杂的工作面形状 ,合理地解决了非规则采矿工作面积分区间的划分问题 ;同时 ,给出了工作面形状系数的计算公式 ,整个计算过程利用计算机技术实现自动解算 ,避免了对任意曲边形工作面采用矩形分割的近似处理方法 ,提高了地面沉陷预计精度。最后 ,用实例说明了本文提供的对非规则采矿工作面的处理方法比现行处理方法具有更高的精度。
