Confirm materials and quantities on invoices, work orders and bills of lading. Identify upcoming work locations and blast areas in monthly mine operation schedules. (2)
  • Locate mine details on maps. For example, identify current and planned blast areas, bench numbers, changes to ramp roads, current loading areas and planned development areas when determining work plans for shifts. (2)
  • Locate data in graphs. For example, view line graphs showing ground vibration levels resulting from blasts. View bar graphs showing daily production totals for each piece of equipment and for day and night shifts. (2)
  • Locate parts and task sequences in assembly diagrams. For example, identify construction and disassembly sequences for crushers and other equipment. (2)
  • Locate data in lists and tables. For example, supervisors in granite quarries scan various lists to locate identification numbers of granite to be shipped, verify equipment availability and confirm that operators' have completed their daily vehicle inspections, initial drill rig checks, blasting inspections and reviews. They may review analysis tables which show chemical compositions and types of rocks being mined. (2)
  • Complete entry forms. For example, record quantities and costs on purchase and requisition forms when ordering new personal protective equipment and replacement parts for equipment. Complete workplace audit forms during safety inspections. Record types, locations and quantities of materials moved by equipment on daily production reports. Summarize crews' hours and enter rates of pay on payroll forms. Enter dates, times and names of people involved in incident and accident forms. Record preparatory activities and planned drill hole patterns on blasting reports. (3)

Job Task Planning and Organizing
  • Supervisors of mining and quarrying are responsible for planning and organizing their own job tasks within the requirements of mines' production plans. They attend shift exchange meetings to understand previous shifts' accomplishments and learn about any disruptions that may require adjustments to their shift plans. Throughout their shift, they often make adjustments to their schedules in response to production slow-downs, equipment breakdowns and changes in the weather. Supervisors of mining and quarrying are responsible for the planning, scheduling and dispatching of operators and equipment to meet daily production goals. They also participate in the planning of mine operations. (3)

Decision Making
  • Choose assignments for equipment and operators. Assign operators to equipment according to their qualifications, experience and availability. Choose tasks and locations for equipment according to production requirements. (2)
Back to Top

Problem Solving
  • Production targets cannot be met because of equipment malfunctions and the low quality of materials at current mining locations. When equipment breaks down, call mechanics and outside service contractors to carry out repairs. When yields are below targets, inspect sites, review engineering plans, analyze historical yields and discuss your findings with mine managers and engineers. In some cases, move operators and equipment to other areas of mining sites. (2)
  • Production plans cannot proceed because of unsafe work conditions. Ask operators to complete tasks such as breaking-up frozen rock piles, clearing blocked roadways and digging deeper drainage ditches to prevent water overflow. Re-position equipment and reassign operators in response to environmental safety concerns such as high levels of methane and fuel spills. Restrict access to these areas until air quality readings are within acceptable ranges and fuel spills have been cleaned up. (3)
Back to Top

Finding Information
  • Find information about safety regulations from mining legislation and the organization's policies and procedures manuals. (2)
  • Find information about previous shifts by speaking with 'cross shift' foremen and reading incident reports and production schedules. (2)
  • Find information about production levels by speaking with dispatchers, reviewing data in computerized mining modules and speaking with operators. (3)
Back to Top

Critical Thinking
  • Evaluate efficiency of production processes. Review production figures for each operator and piece of equipment. Examine the causes of operator and equipment downtime and delays due to bad weather and poor road conditions. Make assessments within the context of daily, weekly and monthly production goals for the mine. (3)
  • Assess the safety of mining operations. Observe crew members and equipment at work. Confirm the use of personal protective equipment and check to see that standard operating procedures are being followed. Review equipment and inspection logs and incident and accident reports. Talk to operators to ensure they are alert and fit for work. (3)
