AAMC.001.005.1275
JULY 2019 GRASSTREE GM SUMMARYHighlightsSafety Reset Completed• Strong participation and engagement from all crews and
contractors.• Good feedback and improvement opportunities.Gas Drainage• Compliance achieved for MG and TG of 808 panels• Drilling and drainage plan in front of full block forecast.
Longwall Production in front of Forecast• Production ahead of schedule for the month• Longwall rundown running on plan
onli nfi a I
Lowlights
Safety Performance• 1 x Lost Time Injury — CMW struck head on 1T stone dust bag.• 5 x HPI's reported• 2 x HPH's reported
Development Production Below Forecast• Development behind by 154m for the month• Slipped 3 x days against MOP 7 schedule(Does not impact 808 start up but flows onto MG910 delivery)
Grasstree Carbon Emission Tracking• Less efficient venting strategy to mitigate LW gas delays have
resulted in higher CH4 venting direct to atmosphere (greater useof venturis)
-1=1- Emerging Issues
Critical Role Vacancies: Attraction and Retention of critical rolesthrough to the end of mine life.• Current Positions Vacant: 15 critical roles• Mean Time to fill position: approx. 80 days
Longwall Move Preparedness• All equipment onsite and ready for transportation• Schedule developed and getting reviewed and updated daily.
Capcoal Village capacity constraints / Action Plan• Overflow requirements (Aug-Dec) max capacity 122% in Oct• Fatigue Action Plan for Q3 (incl. Dashboard)• Budget associated with Fatigue provisions
Key Priorities
Safety Drive: Continue SafeStart and complete in 03
Longwall Move planning and execution• Planning well advanced• Detailed interaction management required with complexity
around multiple concentrated activities
808 Gateroad Completion• Deliver fit for purpose gateroad — longwall ready• Integration of pre-install, development and installation activities• Efficient demobilisation and restablishment of development

Critical Control Deficiency /
ImprovementIssues / Comment Response
1. Stone dusting LW909TG 30% Pass rate for June LW909 Belt Road 70% Pass rate for June
All failures are re-dusted within the time frames required by procedures. Increased stone dusting application triggered by the high failure rate due to this critical control. Ongoing
2. Real time gas monitoring
Gas monitor inbye the last open cut through of the longwall was found to be not relocated each pillar move as required under the SHMS. The paperwork and instructions were given, but not executed by the relevant electrical coordinator.
Sensor moved to correct position and CMW counselled. Complete
3. Design and Selection of Fit-For Purpose scaffold
3x separate scaffolding setups inspected, all were compliant (Scafftags etc) except 2x did not have JSA’s in place as required under the SOP
Action raised to resolveComplete
4. Fit for purpose equipment Hydraulic
Found 3x minor non-conformances to MOP 1. Some refurbished Cyl returned to site with steel caps instead of plastic, 2. Recently delivered to site hosing left in sun 3. Audited hosing did not identify test pressure on ID tag
Action raised to follow up all 3Ongoing
5. Register of Confined Spaces and Permit to Enter
GMF002 confined space task No rescue plan in place on the permit or on the JSA, no sign off on completion by the Permit issuer. The usual rescue plan was in place but not documented.
The procedure has been reviewed with persons allocating and supervising this work. Complete

There is reduction in rate planned in LW910 due to the Ryan dyke and Maloney dyke.Improvements to slowdowns for LW909 – these are AFC chain feedback and CH4 at the shearer. We have seen approximately 157Tph benefit in LW909Mods for LW808 – These mods have been completed in the overhauls, key changes;• Removed the neoprene guard on shearer and replaced it
with conveyor (more robust, ridge and longer wearing) this will allow more accurate general body monitoring of the CH4 coming off the chain.
