"El Chiflón del Diablo", from collection "Sub-sole", by Baldomero Lillo, is a story set in the coal holdings of Lota and Coronel -Chilean ports in the province of Concepción- to late nineteenth century, which calls into evidence of social inequalities arising from human labour. On the one hand is the excessive zeal of the owner of the mining company to increase their profits by reducing operating costs -including those necessary for the safety of people- and, secondly, the manipulation of the worker’s need to conserve its labor source for their livelihood, to bring them obedience and submission.
The descriptive framework employee underscores the anxiety of María de los Ángeles, the elderly mother of "Copper Head" (Cabeza de Cobre), which has already lost her husband and eldest sons in accidents in the mine, she and her only surviving son, that the author characterizes as a boy whose hair has reddish led to the nickname that is recognized by the community. "Copper Head" , under the suggestion of severance provided by the foreman of the mine, along with other two workers, agrees to assume the risky work that others shun in pique (mining work underground sector) known as "the devil''s chiflon" ( "Chiflon": collapse stone dropped into the interior of a mine. It also defines a very subtle flow of air or wind crept through a pipeline accident or material), but such an eventuality hidden his mother, not to increase the pain of memories -being lost during their work in extracting coal, which is internally by socavones (mining holes) kilometres under the ocean. The "Chiflon" has a bad name among miners by the precariousness of supports made in socavones , scarce and of poor quality for reasons of economy, which has already caused the death of many workers. Arrive the drama of a new collapse in socavón , and as many times as it did previously, María de los Ángeles, as other women and children in the village, fearful to go listen the alarm. Again, María de los Ángeles has to pay to the greed of mining the sacrifice of the lives of their last child; aware of the fatal news, on the edge of the mouth of the mine takes his imagination to reconstruct the circumstances in which the collapse happens again and listen to the voice of his son that the flame from the maze of tunnels. His anguished mother instinct and love does the rest, and precipitates in the depth of the well. Of which escape as breath of a monster blood thirsty.
