摘要
以2161(1)下顺槽贯通测量工作为例,介绍了在顶板破碎、测点极不稳定情况下,通过合理选择测量方案及测点设置方法,确保了长距离巷道的贯通精度,对类似条件下的巷道贯通有着重要的指导意义。
Take the example of 2161 （1） coal face go- through survey, introduces how to choose a measuring scheme and the method for setting measuring - point in order to insure the precision of transfixing a gateway in long distance, on the situation of brocken roof and extreme astatic measuring - point. It has an important guid- able significance for the similar one.
