通过对我国各主要煤田地表移动观测成果的分析,使我们认识到了一个描述地表移动盆地的新的规律:各地表点的移动矢量,当把它们的原点聚集到一个给定点上时,就会形成一个规则的椭园(图一a).这个规律是在地表和覆岩内部各种不同的条件下查明的,它可靠地适用于一个已经稳定了的位移盆地形态. Through the analysis of the observation results of the surface movement of all the major coalfields in our country, we have realized a new law that describes the surface-moving basins: the movement vectors of the surface points around each other will form when their origin is gathered to a given point A regular ellipse (Fig. 1a). This law is identified under various conditions within the surface and overburden, and it is reliably applied to a stable displaced basin pattern.
