A team of women from Missouri University of Science and Technology has won another world championship in mucking.

The Lady Miners finished first in the women’s division at the 2011 Intercollegiate Mining Competition, which was held March 16-19 in Reno, Nev. The competition features events based on mining techniques used in the late 19th and early 20th centuries. Students compete in timed events like gold panning, surveying, hand-mucking, hand-steeling, track-standing, Swede sawing and jackleg drilling.

“I like doing the same activity as the boys do,” Catherine Walker, a senior in mining engineering at Missouri S&T., told the New York Times. “Most people would never see a woman jack-legging.”

Approximately 25 men’s and women’s teams from around the world participated in the annual competition. Missouri S&T placed third in the men’s division.

The Missouri S&T women previously won world championships in 2009 and 2007. S&T also won world titles in men’s and women’s mucking in 2004 and 2005.

The debris left over from a mining blast is known as a muck pile, and that’s where the term mucking comes from.

Members of Missouri S&T’s 2011 championship team include Erica Fay, a junior in mining engineering from Arnold, Mo.; Jenna Freese, a sophomore in mining engineering from Ozark, Mo.; Kaley Frizzell, a sophomore in mechanical engineering from Salem, Mo.; Rachel Kautz, a junior in petroleum engineering from Kansas City, Mo.; Margaret Newsom, a freshman in mining engineering from Springfield, Mo.; Katherine Stockdale, a junior in geological engineering from Dixon, Mo.; and Catherine Walker, a senior in mining engineering from Kansas City, Mo.
