A difficult and time-consuming rescue process was ongoing early Wednesday for dozens of Freeport Indonesia employees and
contract workers trapped in a tunnel collapse.

RENO (MINEWEB) –
Freeport Indonesia reported Tuesday that rescue workers from the company have evacuated 10 of 37 people believed trapped in a collapsed tunnel section in an underground mine training facility in the Big Gossan tunnel, outside of the Grasberg copper and gold mine.
The company confirmed that two people were killed, four other employees were evacuated and three escaped unharmed. Two of those evacuated were reportedly in stable condition in the Tembagapur Hospital.
A total of 40 employees and contract workers were in a classroom at the mine training facility when part of a tunnel collapsed at 7:30 a.m. Tuesday morning. Three persons managed to escape immediately. All of those trapped are male. The tunnel is 500 meters (1,600 feet) away from one of the Grasberg mining areas.
It took 10 hours for the rescue team to dig through the tunnel to reach the miners.
“We don’t want to be careless because the terrain surrounding the old tunnel is prone to collapse, said Papua police spokesman Lt. Col. Gede Sumerta Jaya. He noted that the reason for the collapse remain unclear.
A member of Indonesia’s House of Representatives, Daryanto Toto, told the news website Republika Online that the Ministry of Energy and Mineral Resources, the Ministry of the Environment and the police immediately form a team to investigate the cause of the landslide to determine if it is a natural disaster or caused by human error.
“Our first priority is to make every effort to rescue trapped workers,” said Rozik Boedioro Soetijipto, president-director of Freeport Indonesia. “We extend our heartfelt condolences to the families of the deceased.”

MSHA anticipates publishing a final, new coal dust regulation in June 2013. A new exposure imit, proposed in October 2010, contemplates a 50% reduction from the current exposure limit (2 mg/m3) to 1 mg/m3. The accompanying “ancillary” regulations would limit mine operator dust control methods, mandate a new and unproven dust sampling device, extend and complicate an
unreliable sampling and analysis system, impose significant new costs, and pose extensive and unwarranted enforcement actions. Yet, the record is clear that the current coal dust limit protects miners. The extensive industry comments, data and studies submitted to MSHA by the National Mining Association and various companies demonstrate that the agency ignored the massive health protection gains achieved by industry and miners under current regulations, while failing to address statutory mandates needed for improvements, in favor of an old, tired and outdated regulatory approach—“less is more”—that ignores science, logic and law.
The most offensive example of logic and law defied is the agency’s proposed decision to reject mandatory X-ray surveillance for current miners, the best tool for intervention and prevention. MSHA simply ignored government data showing the voluntary X-ray participation rate at between 20%-35%.
MSHA’s 50% dust limit cut relied on a 1995 NIOSH study, a 1996 Advisory Committee report and a 2010 agency “risk assessment.” But, the rulemaking record is filled with studies demonstrating that the risks reported in these documents, if accurate, could only have been created by “hot spots,” in limited areas in three states where excessive silica exposures were documented. Rather than acknowledging its silica control and enforcement issue, and acting to address it, MSHA defied logic and science with its industry wide and ineffective coal dust reduction proposal.
Again and again the MSHA proposal failed to adhere to sound science and law. MSHA rejected the uniformly adopted, OSHA “hierarchy of controls” concept that addresses health concerns with feasible engineering controls, administrative controls, and respirator use when the other control methods do not work or are not feasible. Instead, MSHA imposes regulatory burdens while failing to advance health protections. Perhaps worse, while seeking new technology in the proposed new dust sampler, MSHA failed to demonstrate it was technically sound and feasible, and ignored extensive documented problems with units tested in the field.
Accurate dust samples and analysis are required to properly identify risks and the need for protective measures or enforcement. Yet, the MSHA proposal would replace the current five-sample dust collection method with a “single-shift” (administratively convenient) sample enforcement system. In addition, MSHA would use samples for enforcement, regardless of any process to assure that they actually contain particles that can be inhaled into the lungs, and are not contaminated with oversized, non-respirable particles.
Only in Washington, D.C., could the word “accurate” be deemed to mean, within 25% of the true value, 95% of the time. Yet that is precisely the logic MSHA needed to justify the five sample averaging system. By reducing the quantity of samples, relying on a single sample, and failing to ascertain if samples contain oversize particles, MSHA will achieve more enforcement, regardless of accuracy, and again redefine “accurate” to defy logic and science.
Once these concerns were raised by industry, Congress prohibited MSHA from finalizing the respirable dust rule until the Government Accountability Office (GAO) reviewed the basis for the MSHA proposals. Unfortunately, the GAO review was not an independent review; it parroted MSHA’s conclusions and is permitting MSHA to advance its rule further, perhaps later this summer.
Over the last six months, MSHA added ventilation plans and respirable dust compliance to its Impact Inspection program, including targeting 13 mining operations for impact inspections due to an alleged history of respirable dust compliance problems. Undoubtedly, MSHA dust citations will permit mine operators to cross examine MSHA enforcement and lab personnel on the validity of dust sampling procedures, and the validity and accuracy of weighing and analysis conducted by MSHA lab personnel. In prior cases and led by our firm, citations have been vacated due to inaccuracies and deficiencies in the MSHA system producing results that cannot carry MSHA’s burden of proving a violation. The MSHA coal dust regulations, if issued as proposed, likely also will present a court with the
opportunity to examine whether regulations that ignore sound science and logic should be upheld or rejected. We are confident that unless the agency vastly improves its proposed rules and procedures, courts will strike down rules and enforcement that defy logic, science and law. The legal arguments rendering the MSHA proposed rule invalid, if adopted, were well documented in the industry comments and form the basis for a court’s rejection of the rules, should they be issued as proposed. Unfortunately, if MSHA acts as expected, it will have wasted significant resources and missed an opportunity for needed regulatory and enforcement
