近年来,我们施工了几个倾角不同、断面较大的斜井,由于井壁开凿的不够平整,经常出现凸出或四缺等现象,因此,用悬挂半圆坡度规给斜井腰线点难于施工。后来,我们改用经纬仪来给定斜井腰线点。实践证明,这种方法有一定的灵活性和优越性,它不仅可以克服井壁不平而引起的给点误差,而且可以随时测定其腰线点的三个座标,能及时检查纠正。坡度规方法一般用于次要巷道如溜矿天井,或通风天井,而经纬仪用于主要巷道如主、副斜井等。 In recent years, we have constructed several inclined shafts with different angles of inclination and large cross sections. Due to the lack of smoothness in the shaft lining, bulging or four missing phenomena often occur. Therefore, construction. Later, we switched to the theodolite waistline point using a theodolite. Practice has proved that this method has a certain degree of flexibility and superiority. It can not only overcome the unevenness of the borehole caused by the point error, but also can measure the waistline of the three coordinates at any time and can timely check and correct. The slope gauge method is generally used for secondary roadway such as sliding mine patio, or ventilated patio, while theodolite for the main roadway such as the main, auxiliary shaft and so on.
