Methane Regulations Archives - Qld Mining Crisis

Grosvenor 29 LW Methane HPI’s in 2019 and 14 in 2020 before the Ignition on May 6th. What happened to May 2018 “It was also acknowledged that continued HPI’s with Methane greater than 2.5% was not satisfactory and the mine must ensure that such HPl’s are minimised, and preferably eliminated going forward.”? SWEET F… ALL!

It was also acknowledged that continued HPI’s with Methane greater than 2.5% was not satisfactory and the mine must ensure that such HPI’s are minimised, and preferably eliminated going forward.…

The INACTION of the MINES INSPECTORATE at Grosvenor, gets ONLY One Recommendation. Resources Safety & Health Queensland (RSHQ) reviews its risk profiling and response practices with a view to ensuring that it operates as a proactive regulator. How weak a response is that?

There are a number of Findings and Recommendations in the Grosvenor Report that mention the RSHQ GROSVENOR REPORT FINDINGS It is only Recommendation 5 that addresses the Mines Inspectorate (RSHQ)…

Following exerted pressure from the Department and greater recognition by Mines of the hazard of elevated methane levels, substantially more effort and investment had been made into methane drainage capacity and efficiency. This was clearly increasing the amount of gas drained, decreasing operational downtime by early intervention to avoid exceedances rather than cutting to trigger trip events. Most importantly risk was being reduced.

Between the 6th and 8th of January there were Five (5) methane HPI’s in the Tailgate of LW 102. The first when the Longwall had retreated 29m and the last…

82 cubic metres per second of ventilation on Grosvenor LW101 Face in September 2016 to dilute methane below 2.5%

July 15, 2021

The quantity of ventilation across the longwall face between 70 and 80 cubic metres per second was a topic of discussion at the Grosvenor Inquiry. Principally this was about the…

Methane level in the Tailgate Roadway General Body is greater than 2.5%, yet at the tailgate drive methane is typically 0.5% or less. What affect do Three venturis and two ventilation curtains face side have?

July 15, 2021

One matter that deserves discussion is Inspector Marlborough about how the methane level in the Tailgate Roadway General Body is greater than 2.5%, yet at the tailgate drive methane is…

“I explained that it was not acceptable to move the LW Shearer when the general body Methane concentration in the TG return is equal to or greater than 2.5%.” Les Marlborough, Inspector of Mines. 20th October 2017

July 14, 2021

Today (20th October), I, Inspector of Mines, Leslie Marlborough, attended a meeting at Grosvenor mine to collect data requested from the mine in a postal mine record entry issued to…

The risk assessment does not mention the risk of an ignition of Methane as a potential hazard. This has to be a major hazard when considering Methane levels of in the TG, as the primary source of the methane is the Longwall goaf gas, which inevitably will flow in the vicinity of the chain pillar rib line.

Inspector Marlborough next MRE about the Grosvenor Procedures for GRO-750-TARP-General Body Contaminant is dated the 13th of October 2017 I found this sentence of the MRE about how the Grosvenor…

“The Level 2 and 3 triggers for Methane for the Longwall return that require the Shearer speed to be reduced by 30% or to stop the shearer do not occur when the shearer is in the TG Shuffle Zone; Has the Methane ignition risk been assessed for this in the risk assessment when developing this TARP?” Les Marlborough Inspector of Mines 12th September

July 14, 2021

Now Mines Inspector issues a written Section 168 Directive to Grosvenor Mine SSE on the 12th of September 2017. The mine is to review the GRO-750-TARP-General Body Contaminant and the…

2017 Methane HPI’s at Grosvenor Mine

July 13, 2021

I have collated all the Methane HPI's from 2017 I possess and they are in the link below. Methane HPI's Grosvenor 2017 Some of the ones that stand out include…

Dobson Methane S166 Directive Dec 2016 does not force Grosvenor to take action about controlling methane. All it does is tell the Mine to make sure workers are withdrawn to a place of safety when Methane >2.5 in each place used by a person for normal work or travel and it is immediately reported to the Inspectors.

July 10, 2021

I do not believe that the wording of Inspector Dobson's Directive is even appropriate for using a Section 166 Directive to reduce risk. What exactly was the intention of the…
