They will also be compatible with the post-mining land use.
Listed below are two general plans for road reclamation, depending
on the ability of the fill slope to handle the restoration of
original drainage patterns . It must be assumed at this time that it
is necessary to maintain access to the portal areas to monitor
reclamation success and to reach private property.
Plan A - Fill slope unstable
As discussed in the January 1994 slope stability report , many
existing, steep fill slopes cannot handle runoff water from the
roads and the areas above. The lack of cohesion of the material and
the steep slopes make the slopes vulnerable to gully erosion and
potential failure. In areas such as this , it is important to
maintain the existing drainage patterns of the roads , where all
runoff from the roads and above is channeled into an inside ditch .
At intervals , the ditch water is passed to the downhill side of the
road through a variety of methods , which are outlined in the items
list below. In areas such as this , where the fill slope is steep ,
sparsely vegetated and the soil is vulnerable to severe erosion ,
the proposed road reclamation is shown on Cross---Sect-ion-A. In this
case, the inside ditch would be moved to the middle of the road . it
should not, however, be located at the junction of the original
ground and the fill slope. The inside portion of the existing road
would be re-graded toward the ditch and this area would also serve
to catch material that collects from the cut slope. The outside
portion of the existing road (outside the ditch) would grade to the
ditch to continue to keep water off the fill slope. It is likol�
that the majority of the roads will fall into this category .
Plan B - Fill slope stable
In other areas, the fill slope is more stable. The slopes are less
steep ; better soil material has developed; substantial vegetation
exists and water can be passed to the fill slope without the threat
of massive erosion and failure. In these areas , the proposed
reclamation is shown on Cross-Section B. As shown, the entire road
surface is graded to the outside edge, thus re-establishing
original drainage patterns. All culverts could be removed or
p 1 ugged for th i s case. I f a threat of concentrated f l ow on the f 1 at
surface will likely rut and interfere with access , Plan A will be
employed.
