Talk:Quecreek Mine rescue

This page needs some editing.

More than what I'd be comfortable with doing. Some sections seem lifted from a book or news report, and do not sound encyclopedic. Adam850 (talk) 23:28, 17 July 2009 (UTC)

Accident and rescue

It does need better writing, especially the Brief history section, but the chronology of the Accident and rescue sec. seems somewhat confusing. Daniel1212 (talk) 05:05, 24 January 2010 (UTC)

The problem is that the article states,

"At approximately 9 p.m. on Wednesday, July 24, the eighteen miners are in danger 240 feet (73 m) underground, below the fields of Dormel Farm. when the flooded Saxman mine was breached as the mining progressed eastward...These miners were able to escape at around 9:45 p.m. and alert others, and a [[911 call was made at 9:53 p.m."

"As pumps worked to discharge the floodwaters from the rapidly filling the mine shaft, engineers and surveyors worked to pin-point the presumed location of the trapped miners, translating subsurface mine maps to locations at ground surface, and the miners’ families assembled at the Sipesville Fire Hall were informed of rescue plans.

Based on GPS measurements, a 6.5-inch diameter borehole was begun at 2:05 a.m. The borehole was drilled to allow air to be pumped into the mineshaft where the miners were presumed to be: at the most up dip location near where the Saxman mine was breached. On Thursday, July 25, 2002, at 5:06 a.m., approximately 8 hours after the breakthrough, the 6.5-inch hole was drilled into the mine."

However, it also states that

"At 8:33 a.m. Thursday, the first of several diesel pumps arrived at the mine site. Work proceeded immediately to install them in the pit as they arrived. Before this pump arrived, only two submersible pumps were operating in the sump area of the pit. At 11:05 a.m., water was four to five feet deep in the mine pit entrance. Water in the pit reached a maximum elevation of 1856.8 feet at approximately 4:00 p.m., Thursday, July 25.

High-capacity diesel pumps were installed in the pit and put into operation in the afternoon. A 6-inch drop in the water level was reported between 4:00 and 6:00 p.m."

Thus one account has pumping going on before the GPS location was determined, and the airhole drilled approx. just 4 hours after the 911 call, while the article states that the first of several diesel pumps did not arrive untill 8:33 a.m.Daniel1212 (talk) 22:51, 24 January 2010 (UTC)

Worked to make a better comprehensible chronology, and added much context.Daniel1212 (talk) 16:47, 25 January 2010 (UTC)
