Journey to traffic management LEADING PRACTICE Speaker: Buyisile Breakfast Date: 23 May 2017 Venue: Kathu Country Club
CONTENT • Brief Background • Accident and Fatality Analysis • Expert Risk Model • Planning workshop • Potential Adopter Mines
BRIEF BACKGROUND Transport and Machinery Industry team Initial Industry team Recent industry team
BRIEF BACKGROUND Transport and machinery industry team TRANSPORT & MACHINERY MOSH Adoption Team (Specialist) + 2xManagers + Industry Team Hard Rock Industry Team Open Pit/Cast Industry Team Underground Coal Industry Team
TEAM ACTIVITIES • Team was established in 2013 • Meet once a month for +- 5 hours • Initial discussion on whether PDS should be the focus or not • Accident analysis • Fatality analysis • Expert risk model • Preparation of risk report • Visited • Mogalakwena - Motion inhibitor and bumper, Guardvant • Middelburg Colliery – Traffic Management, DSS • Fatigue – De Beers, CSIR, Kolomela • Preparation for Planning Workshop
Accident and fatality analysis Accident and fatality analysis Outcome of the Accident and Fatality Analysis.
Accident analysis Accident analysis • The team set out to use in-house company information to analyse all T&M related lost time injury events • Information from companies could not be collated as it was provided in MS WORD format.
fatality analysis Fatality analysis • In order to focus on the risks that have the most severe impact on T&M safety the team did a fatality analysis. • The team obtained spreadsheet version of the T&M accidents and incidents reported to the DMR for the period 2008 to 2012. • This enabled analysis since the DMR reporting is standardised. • The team THEN identified causes of fatalities as opposed to the root cause of a fatality. • The Open cast/pit information was then separated from the rest of the T&M information and the outcome was as follows: • 35 people were killed in 34 accidents over the 5 year period.
fatality analysis Fatality analysis (Continue) • 45.7% of fatalities happened at a speed (>8km/h) • 40.0% of fatalities happened a speed (<8km/h) • 48.6% of fatalities were the operator or driver of the machine. • 45.7% of fatalities could be ascribed to undesired behaviour. • 25.7% of fatalities could probably be ascribed to fatigue.
fatality analysis Continue 51.4 % of fatalities were caused by either a Front end Loader or a Hauler/dump truck. • 37.1% of fatalities were as a result of hauling activities (haulers/dumb trucks. • Only 17% of accidents happened at global operations with 83% at operator/local operations. • 34% of fatalities occurred on haul roads, 6% at tip areas, 6% at workshops and 20% in pit areas. • 34% of fatalities were non-specific with regards to location.
Fatality analysis Outcomes Cause of Poor Traffic management • Older mine design principles-legacy projects • Mine capacity expansion increase risk. • Contractors – larger fleets of smaller vehicles • Smaller machines were found to be more vulnerable. • Inappropriate application of industry standards. • Visibility around vehicles • Poor Safety Culture • Restricted space for mine to design optimum separation • People walking/being where they should not be • Drivers not adhering to safety rules • Production / Safety focus • Enforcement of rules / compliance
Fatality analysis Outcomes • Global operations outperform local/owner operated operations at a ratio of 1 to 5 when it comes to T&M fatalities. • Load and Haul are the most dangerous TMMs on Open Cast/Pit T&M operations. • Haulers/Dump Trucks caused the most T&M fatalities in open pit/cast operations. (37.1%). • Fatal accidents mostly happen on haul roads (34%) at speeds above 8 km/h with operators/driver by far the most exposed occupation (48.6%). • Undesired behaviour seems to play a major role in fatalities with over 45% of fatalities that can probably be ascribed to that. • Fatigue seems to be the single biggest contributor to T&M fatalities in Open Cast/Pit operations The Main contributors being: • Fatigue • Traffic Management

PLANNING WORKSHOP Planning workshop Planning workshop outcome
PLANNING WORSHOP October 2014 • Objective of the workshop • Select a MOSH Leading Practice • Agreement on the Source mine(s) • Agree the first adopter mine
Planning workshop The team split into two groups focusing into areas which is: • Fatigue • Traffic Management • Local developments • TMM Mining Regulations • Proximity Warning • Collision Avoidance • Stopping of diesel machines • New TMM Guideline • Fatigue Management COP guidelines promulgated Team then decided to focus on Traffic Management
Planning workshop outcomes Team decided that the Traffic Management should be a leading practice with at least the following elements: • Separation/Design Practices for: • Loading • Tipping • Haul Roads • Shift Changes • Workshops • Hard Parks • Field maintenance and repair • Separation Techniques • Physical • Time Zoning • GEO Fencing
Traffic management leading practice development • Industry team developed 18 elements of the Traffic Management Leading Practice • Took long as result of logistics • 1x meeting per month • Members far and wide • Extensive alignment • Local and international sources were consulted
