巷道贯通超前探测预报技术

Advanced detection and prediction technology of roadway transfixion

煤矿地测工作是煤矿生产建设的基础工作,它贯穿于煤矿设计、基本建设和生产的全过程。在井下通常采用全站仪开展巷道贯通的预测预报工作,该仪器虽精度较高,但使用过程中有时会因操作不当导致误差,以致巷道无法精确贯通,造成巨大的经济损失;而通过钻探施工的超前探测预报技术可以较好地保证巷道顺利贯通。

The coal mine geological survey work is the basic work of coal mine production and construction, it run through the whole process of the mine design, basic construction and production. In the underground, usually using total station to carry out the prediction of roadway, the instrument has high precision, but the use of the process, sometimes the improper operation cause errors, and further cause the roadway can’t be accurately excavated through, which cause enormous economic losses, and through the construction of the drilling to predict in advanced, can better ensure smoothly through the tunnel, and has a higher popularization value.
