Case Study: Improving Shovel and Excavator Productivity

INTRODUCTION

Shovel and excavator productivity has been in decline in Australia over the last few years, resulting in unnecessary wasted expenditure. MEC Mining can assist in achieving optimal productivity. A move to optimal productivity can save $0.30 per bcm or $3 per tonne, as well as improving operating and safety conditions at the dig face. Large improvements can be achieved with simple and repeatable measures that concentrate on improving the basic cycle time of components. In other words, increased production can be achieved simply by optimising basic dig area setup and operating parameters. So ask yourself this question: Where does your machine sit on the curve?

BENEFITS TO CLIENT

  • Moving from average to best practice can save $0.30 per bcm or $3 per tonne at a 10:1 ratio
  • Value of additional coal uncovered dwarfs the cost of waste
  • Standardisation improves operating conditions at the dig face with additional safety benefits

OUR SOLUTION

Fundamental improvement in the machine production rates by looking at cycle time components, including:

  • Minimising bench turnarounds and improved access through efficient design
  • Shovel excavator bucket cycle time – optimised by truck position and swing angle
  • Truck exchange time – optimised by minimising turn angles and standardizing practices
  • Bucket fill improved by measures to improve blasting fragmentation and looseness
  • Muckpile shape tailored to each machine type
