Open Mine Workings
Use Open Mine Workings to define a working layer. All underground coal design work, such as drivages, panels and outlines, will be placed in this layer.
The options under the Underground > Coal Reserves submenu will also use this layer for the production of reserve calculations.
Instructions
On the Underground menu, point to Coal Development or Coal Reserves, then click Mine Workings to display the Set Working Layer panel.
Working name
Enter, or select from the drop-down list, the name of the working layer. The chosen layer will be set as the active working for underground coal operations. It does not affect the layer set through the Layer option (under the Design > Create submenu)
To create a new layer, enter the layer name. Layer names use the following conventions:
- may contain up to 40 characters.
- must begin with an alphanumeric character [0 - 9] or [a - z].
- cannot include spaces.
- can include hyphens [ - ], plus signs [ + ], underscores [ _ ], periods/dots [. ].
- can include the special characters of ÁÂÃÀÇÉÊÍÓÔÕÚÜÑ that are used in the Spanish and Portuguese languages.
Description
Enter a description to further describe the contents of this layer. The description can be up to 80 alphanumeric characters and may include spaces. If a description is not entered, then a default description will be used instead. If the chosen layer already has an assigned description, the description will be displayed when the layer is selected. Existing layer descriptions can be overwritten.
To add to an existing working layer, the layer must be loaded onto the screen. If a working layer by the same name already exists in the currently open database, but has not been loaded, then you will be asked whether you want to select the layer or replace it.
Click OK.
The working layer is then opened, and its name displays in the Status toolbar. You can then start generating drivages and panels.
