Crandall Canyon Mine Investigation Report

On 24 July 2008 the U.S. Department of Labor’s Mine Safety and Health Administration (MSHA) announced that it has fined the operator of the Crandall Canyon Mine in Emery County, Utah, $1,340,000 for violations that directly contributed to the deaths of six miners in 2007.

According to MSHA’s media release, Agapito Associates Inc., a mining engineering consultant, was fined $220,000 for faulty analysis of the mine’s design. MSHA cited the mine operator for 11 additional, non-contributory violations issued as the result of the investigation. The proposed penalty for these violations is $296,664, bringing the total proposed penalties against the mine operator to $1,636,664. Crandall Canyon Mine is operated by Genwal Resources Inc., whose parent company is Murray Energy Corp.

Safety At Work magazine covered the incident extensively as it provided a stained mirror to the lucky rescue of the miners from Tasmania’s Beaconsfield mine. I reported elsewhere on the fresh seismology findings.

The MSHA report states that

“Three separate methods of analysis employed as part of MSHA’s investigation confirmed that the mining plan was destined to fail.” (my emphasis)

To a non-US observer the fine seems remarkably light given that the mining plan was critically deficient, 6 people died in the first incident and 3 died ten days later.

Not everyone is happy with how the investigation has been conducted.

MSHA accident investigators have cited Genwal Resources Inc. and Agapito Associates Inc. for the following violations:

  • The mine operator did not immediately contact MSHA after coal outbursts threw coal into the mine openings and disrupted regular mining activities for more than one hour on three separate occasions prior to the August 6 outburst.
  • The mine operator failed to propose revisions to the roof control plan when conditions (coal outbursts) clearly indicated that the plan was inadequate and miners were being exposed to dangerous conditions.
  • The operator violated the approved roof control plan by removing coal that was required to support the roof.
  • The operator’s outside engineering firm failed to recommend safe mining methods and pillar/barrier dimensions, and the operator failed to maintain pillar dimensions that would effectively control coal outbursts.

Beaconsfield mine supervisor’s safety comments

It is reported in today’s Australian newspaper that the coronial inquest into the death of Larry Knight has heard from Mr Knight’s supervisor, Gavan Cheesman.  Mr Cheesman has said that he was not aware of a report of seismic activity at level 925 (the scene of the fatal rockfall) from the previous shift.  If he had

“I would have gone down personally and checked out the area before sending them (Knight, Russell and Webb) in”.

This reinforces the importance of taking time before a job or shift starts to familiarise yourself with the state of the workplace.  In many industries this takes the form of a job safety analysis.  In hospitals there is a handover process between nursing staff.

Mr Cheesman has also said that he believes that the void at levels 915 and 925 was too large and insufficiently supported.  He agreed that the inadequate support contriubuted to the rockfall that caused the death of Larry Knight.

The inquest is continuing.

Managers doing what they think the boss wants

The walkout from the Tasmanian Coronial inquest of the Beaconsfield Mine legal team has given the issues associated with the death of Larry Knight more media prominence than it would otherwise have received.  The withdrawal also allows statements concerning the financial pressures on the mine to continue uncontested. An ABC podcast on the coronial inquest…

Beaconsfield Coronial Inquest Walkout

On 22 July 2008 the Tasmanian Coroner continued with his inquest into the death of Larry Knight at the Beaconsfield mine on 25 April 2006. Shortly after the start the legal team representing the mine walked out. Newspaper, radio and TV have covered this extraordinary development. Other reports in SafetyAtWorkBlog told of the lawyers’ attempts…

Coroner to investigate safety management of Beaconsfield mine

A front page report in the The Australian on 9 July 2008 is reassuring safety professionals who had hoped for OHS management details from the Tasmanian Coroner’s inquest into the death of Larry Knight at the Beaconsfield mine.

According to the report

Coroner Rod Chandler yesterday ruled against the mine’s submission that he should simply adopt the findings of the official Melick report into the Anzac Day rock-fall in 2006 that killed Knight and trapped colleagues Brant Webb and Todd Russell underground for 14 days.

Mr Chandler also ruled against the mine’s fall-back position that any inquest should be limited to geo-technical issues.

Instead, he ruled he would also examine risk management at the mine, which was criticised by an expert’s report, the mine’s “financial situation” and the role of Tasmania’s work safety watchdog.

This puts the inquiry iinto the realms of the Sago mine investigation and many other mine fatality inquries.

The full inquest resumes on 22 July 2008.

Beaconsfield Mine Inquest

An article in today’s Australian newspaper reports on the coroner’s inquest into the death of Larry Knight in the Beaconsfield mine in 2006. It provides the first insight into the OHS report for the Melick investigation.

In October 2005, six months before Larry Knight’s death, the mine was closed after a minor rockfall. It is reported that mine management only allowed workers back into the mine after geotechnical advice.

Professor Michael Quinlan of the University of New South Wales wrote that, from an OHS perspective, this was a poor decision. Whether financial pressures were behind the permission to reenter the mine is under dispute.

Counsel for the mining company, Stephen Russell has

urged the court to exclude Professor Quinlan’s evidence because the University of NSW professor was not expert in geotechnical issues.

Valid point, perhaps, except that the coroners need to investigate deaths from a broad pool of opinion and expertise. I suspect that Michael Quinlan would be the first to admit he is not an expert on geotechnical matters.

It seems from the media report that the counsel for the mine believes that, even though an assessment would involve worker activity in a workplace, occupational health and safety considerations were not necessary at the time.

In an earlier report in the Mercury newspaper, counsel assisting the Coroner, Michael O’Farrell

argued against an earlier move by the mine’s lawyers to confine the inquest to seismic event on the day of the rockfall.
Mr O’Farrell told Launceston’s Supreme Court that attempts to contain the inquiry to a close examination of the geotechnical issues surrounding the collapse did not serve justice, and may lead to error.
He urged Coroner Rod Chandler to consider all types of evidence, “even red herrings”, in order to make the recommendations necessary to prevent similar mine deaths.
The inquest should also focus the mine’s safety processes and risk assessment procedures, as well the capacity of the state government’s workplace standards body, Mr O’Farrell said.

I have stressed elsewhere that I have no problem with companies deciding to do nothing after a risk assessment is undertaken. It is the right of the employer to accept or reject OHS advice. But what I object to is if a company then tries to avoid responsibility for that decision if it turns out to be a poor one.

The mine’s senior counsel, David Neal SC, then asked the Coroner, Rod Chandler, to review the cost-benefit of a detailed investigation into Larry King’s death as the proceedings are costing each party $20,000 per day.

David Neal, also requested 28 witnesses identified by the opposing counsel be excluded. I don’t think that relatives of dead workers would see these costs as an impediment to determining the cause of a loved one’s death. I find it extraordinary that such a suggestion would be made at all.

Pipeline explosion may lead to invocation of emergency powers

This post is receiving a lot of attention from around the world so, although, at the moment, the workplace safety issues have diminished, it is interesting to note that The Australian newspaper for 12 June 2008 reports that the Premier, Alan Carpenter, has acknowledged that he may need to invoke emergency powers to seize control of electricity and gas supplies.

This is an extraordinary development that indicates the infrastructure fragility of Western Australia.

The supply disruption is now also receiving federal government attention as it begins to affect Australia’s ability to supply China’s insatiable appetite for Australian minerals and energy.

Alcoa Australia is the latest company to announce a “force majeure” as a result of the Apache Energy pipeline explosion.

It is phenomenal to see how an event that in OHS terms is a “near miss” has the potential to weaken a country’s economic growth.
