煤矿工作面上方地表经常会出现一些裂缝，确定地表裂缝的分布、宽度及其与水平变形之间的关系，有助于对其引起的地面破坏进行预防和治理。通过对现场实测的裂缝分布情况的研究，得到了裂缝在平面上的分布形态、裂缝在宽度上的分布规律和裂缝与开采引起的地表变形的关系，并给出了相应的拟合公式。研究表明：开采引起的裂缝宽度与水平变形之间存在密切的相关；裂缝区与拉伸变形区对应；裂缝区裂缝宽度之和总是小于水平变形之和，仅有部分水平拉伸变形可以通过地表裂缝反映出来。

A number of ground fissures frequently occur over coal mining work face. Figuring out the relations between ground fissures ' distribution, width and horizontal deformation can contribute to predicting and controlling ground damage caused by fissures. The distribution of ground fissures is studied via field measured data and the relationship among the hori-zontal distribution and distributive regularities in width of fissures,and the relations between ground fissures and coal mining are obtained. Finally the corresponding fitting formula is given. This research indicates that there are a close relationship be-tween ground deformation and the width of fissures caused by coal mining. Fracture zones are corresponding to the tensile de-formation zones. And,the sum of fissure's width is invariably less than that of horizontal deformation and only a small quantity of horizontal deformations can be reflected through ground fissures.
