摘　　要：在露天采矿矿坑监测实践中发现了矿坑平面形状与矿坑稳定性的联系,给出了类椭圆形矿坑、类圆形矿坑、类矩形矿坑的应力与位移监测数据,以实测数据为依据,指出了类椭圆形矿坑、类圆形矿坑的优越性,得出了类椭圆形矿坑优于类圆形矿坑、类圆形矿坑优于类矩形矿坑的结论。介绍了矿坑监测采用的方法和监测过程。The relations between the plane shape of mining pit and its stability has been found in opencast mining pit observation practice. It furnishes observation data of stress and displacement of similar ellipse mining pit, similar round mining pit and similar rectangle mining pit. The superiority of similar ellipse mining pit and similar round mining pit has been pointed out based on site observations. It reaches the conclusion that the similar ellipse mining pit is advantageous than the similar round mining pit, and the similar round mining pit is advantageous than the similar rectangle mining pit. The ways and process of mining pit observation has been given.
