An open cut trench refers to a method of excavation where a trench is cut into the ground to facilitate the installation, repair, or replacement of underground utilities, pipelines, or other infrastructure. This traditional approach involves the removal of soil and debris to expose the area for construction activities. Open Trench Construction:

The initial excavation in the ore body is done to open the stope. Since such excavation is to be carried out without free face, the excavation may be termed as box-cut. In cut and fill method of stoping, the box-cut excavation is done by driving sill drivages. These sill drivages are further extended in the operation of stoping.
