| 摘 要： | 煤矿在下分层巷道掘进过程中,片帮、底鼓等动力地质现象频繁,按一般方法测设的导线点经常发生位移,用深基固定导线点,既可以解决导线点位移的问题,又可减少测量人员的工作量,经济效益显著。

Application of Deep-foundation Fixed-point Traverse Survey in Lower Slice Heading in Coal Mine |
| |
| Abstract: | Dynamic phe-nomenon such as rib fall and floor heave frequently occur in the process of road drivage in lower slice and the traverse surveying points set by general method often displace.The use of deep-foun-dation fixed-point traverse survey not only solves the displace-ment problem of tra verse surveying points,but also reduces work load of surveyors and obtains marked economic benefits. |
