The company uses laser pointer to control the quality of tunnel construction

Recently, Shandong Zhaoyuan Project Department of the company took the lead in the application of laser pointer to control the quality of drift driving in the construction of the drift in Xiadian gold mine, to minimize the occurrence of over and under excavation in the construction process, and to eliminate rework waste, so as to achieve the purpose of improving efficiency and reducing costs.

From the use of the equipment, it not only effectively controls the direction of tunnel excavation, but also accurately controls the height of the top and bottom of the tunnel, which greatly facilitates the independent control of the process quality of the holing workers, and also helps the management and technical personnel to timely understand the quality of the site and control it.
