在矿井联系测量工作中,由于矿区建筑及地形等因素的影响,经常遇到图1所示的情形(如徐州矿务局青山泉矿、淮北矿务局沈庄矿,平顶山矿务局一矿),A B边长大于钢尺整长,且离地面较高,致使一尺段不能量完又无法用直线定线[1]法测量。此时,一般所采用的测量方法是。在A B中间选择若干点并做上标记,利用经纬仪使之与A B在同一垂直面内,测量每相邻点的边长及垂直角下面叙述方便,记为Ⅰ法。这样在A及每一中间点上都要
In the mine contact measurement work, due to the construction of the mining area and topography and other factors, often encounter the situation shown in Figure 1 (such as the Qingshanquan Xuzhou Mining Bureau, Huaibei Mining Bureau Shenzhuang Mine, Pingdingshan Mining Bureau, a ), AB edge length greater than the length of the steel rule, and from the ground high, resulting in one-foot segment can not be finished and can not be used straight line alignment [1] method of measurement. At this point, the commonly used measurement method is. In the middle of A B select a number of points and marked, the use of theodolite so that it is in the same vertical plane with A B, measure the length of each adjacent point and the vertical angle of the side described below, referred to as Ⅰ method. This is done at A and at each intermediate point
