Following the discussion about the Dozer Push Method some time aago in my previous post, in this moment, i'll try to give a general overview of the cost and benefits of this method. and next post i'll explain about the planning and implementation to mine scheduling. The cost-benefit analysis of Dozer Push Method in mining operations primarily arises from reduced dependency on trucks and excavators, leading to lower operating costs. Below is an overview of the cost and benefit considerations: => Cost Savings 1. Reduced Fuel Consumption: • Bulldozers consume significantly less fuel than a fleet of trucks and excavators. • Example: A standard dozer may use 15-20 liters/hour of fuel, whereas a large mining truck can consume 50-100 liters/hour. 2. Lower Maintenance Costs: • Trucks and haul roads require frequent maintenance, increasing costs. • Bulldozers operate in a smaller, more contained area, leading to reduced wear and tear. 3. Reduced Equipment Requirements: • Fewer trucks and excavators are needed, saving on capital and operating expenses. • A single dozer can replace multiple trucks for short-distance material movement (typically up to 200 meters). 4. Smaller Workforce: • Fewer operators are required as the method relies more on dozers than complex truck-excavator systems. 5. Less Road Construction and Maintenance: • The method eliminates or minimizes haul road construction, which can be costly, particularly in rugged terrains. => Benefits 1. Operational Efficiency: • For short distances, dozers can move material more quickly and effectively than trucks, reducing cycle times. 2. Flexibility: • Bulldozers can operate in areas where trucks may not be feasible, such as steep slopes or tight spaces. 3. Environmental Benefits: • Reduced fuel consumption translates to lower greenhouse gas emissions and a smaller carbon footprint. 4. Improved Safety: • Fewer vehicles on site reduce the risk of collisions and accidents, enhancing overall safety. => Potential Costs 1. High Initial Capital for Dozers: • Purchasing or leasing large bulldozers can require significant upfront investment. • However, the long-term savings often outweigh this cost. 2. Limited Efficiency Over Long Distances: • Dozer push is cost-effective only for short distances (typically less than 200 meters). For longer distances, trucks and conveyors are more economical. 3. Steeper Learning Curve: • Operations may require retraining of personnel to maximize the efficiency of dozer push operations. => Conclusion The Dozer Push Method offers significant cost savings in the right conditions (short distances, suitable slopes) and is particularly effective in shallow mining operations. However, a detailed feasibility study should evaluate specific project conditions to determine the exact cost-benefit ratio.
