• Description:
  "The capital investment and operating costs of two methane-control systems used during longwall mining operations are compared in this Bureau of Mines report. Costs are given for a surface gob hole drainage system and an underground cross-measure borehole drainage system to control methane gas in gobs in four coal mining areas- central Pennsylvania, northern West Virginia, southern Virginia, and northern Alabama. Present-worth analysis is used to determine the more cost-effective alternative in each location. The alternatives have equal lives and provide the same service based on a minimum rate of return of 15 pct. In central Pennsylvania and northern west Virginia, the gob hole system is more cost effective than the cross- measure system, by 10 and 18 pct, respectively. In southern Virginia and northern Alabama
  
  the cross measure system is more cost effective, by 29 and 38 pct, respectively. Costs for other locations must be developed on a case-by-case basis." - NIOSHTIC-2
