current status:
1. The underground workings have been blasted.
2. It is unlikely this area will be mined.
3. The area is now stable, but needs some growth medium.
4. The 1994 calculations are updated below.
Total Area 5.7 acres
Ave. backfill x-sec area = 450 sq ft
Length of backfill area = 900 feet
Volume of backfill area = 405000 cu ft
Volume of backfill area = 15000 cu yds
Cost per yard = $1.25
Backfill cost = $18,750.00 1994 amt = $9,000
Ave. topsoil depth = 0.5 feet
Volume of topsoil needed = 124146 cu ft for 5.7 acres
Volume of topsoil needed = 4598 cu yds for 5.7 acres
