Economic Modeling of Australian Longwall Ventilation
The goal of optimum longwall ventilation design can be seen as an integral part of the success and continuation of entire mining operations. The process of longwall ventilation design is ideally an integral process to the overall mine design development and implementation. To develop optimized longwall ventilation designs in this context an economic basis has been established to evaluate and undertake further design iterations to achieve the goal of design optimisation. Fundamental economic consideration of longwall ventilation design characteristics and operation through the analysis of current longwall ventilation practices is used to outline the basis for a generic economic longwall ventilation model. Some of these issues include gateroad development, sealing practices, labour utilisation, ventilation infrastructure, operational delay costing and consideration of alternate ventilation techniques such as booster fans and bleeder ventilation. The economic investigation of longwall ventilation draws on aspects of the established longwall ventilation practices from North America, Europe and Australia.
