1. An Example of Drawing Hard Rock Room and Pillar in MineSight ©2012 Dr. B. C. Paul Note – The screen shots in these slides come from the program MineSight developed by Mintec. Many of the operations demonstrated herein can also be found in Mintec training courses. Appropriate credit to the software developers is given.

2. What I Will Draw I will be drawing a grid of 50 ft wide openings with 50X50 pillars. The mine workings will have 3 levels, each 30 ft high. –The top level will advance with jumbos –While the lower levels will be taken out as benches.

3. The Approach I will develop a gridset I will snap an edit grid to the gridset at the top of my room and pillar openings I will set my snap to the edit grid I will draw in centerlines for my entries as polylines snapped to the edit grid I will use opening templates with the polylines to guide them I will use an intersect solids tool to merge drives and cross-cuts.
