Feasibility of controlled ventilation
The high cost of mine ventilation can be reduced by increasing the degree of control through improved planning, using currently available resources. Analysis programs have been developed to complement the VENT program, already widely used in British Coal in the planning of ventilation circuits. Potential savings have been demonstrated by the use of underground boosters, by switching off excess capacity at weekends and holiday periods and by greater use of variable pitch, variable speed fans and of fan efficiency characteristics, as well as good "housekeeping" procedures. High quality continuous monitoring is an essential adjunct to the control process. The following environmental constraints have been identified: control of gas levels, dust, spontaneous combustion, heat and frictional ignition.
