Up to three gob vent boreholes GVBs are required over each longwall panel.
Additionally, exploratory holes will be drilled within the permit boundary. Run-
offfrom the related drill pads may not go through a treatment facility such as
a sediment pond. Run-off from the pads that does not report to a sediment
pond will be filtered through a sediment fence. Design of sediment fences
for three drill pad configurations are presented in Volume III, Exhibit 8
beginning on page Exh-8 - 107. The three typical drill pads are designed on
a 3H:1 V slope, 5H:1 V slope and 10H:1 V slope. The typical sediment fence
configuration, berms and ditches for the various slopes and pad sizes are
shown on Maps 36 and 36a..
The following table lists each gob vent borehole and its design drill pad.
