Fire, the oldest combustion problem, is a major cause of human suffering and material loss, and the one that perhaps we predict the least accurately (Fernandez-pello, 1994). A major reason for this is the complexity of the problem itself. Tremendous progress has been made in the last two 706 Data Mining III.

The prediction of the coal mine fire response time, defined as the remaining time before conditions at attack positions grow untenable for firefighters, plays a vital role in the decision-making process during a mine fire scenario. The knowledge of the response time along with the fire size, fire location, and arrival time could allow for the most …

Since 2000, more than 150 underground mine fires have occurred in the United States. In fact, three of the mine fires since 2000 resulted in subsequent methane explosions. Two mine workers were …

The formerly busy burg has turned into a ghost town. The cause was something that's still happening beneath Centralia's empty streets: a mine fire that's been burning for over 50 years ...

The basic idea behind fire mining is that if you get a rock hot enough, it'll break into smaller, more manageable pieces. To accomplish this, I got a good wood fire …

Cyprus Plateau Mining Corporation's Willow Creek underground mine near Price, Utah. Forty-five miners evacuated. The mine was sealed and inert gas injected into the fire area. The mine reopened and twenty months later, on July 31, 2000, two miners lost their lives and eight miners sustained injuries due to a fire and explosion.

A theoretical evaluation was made of the usefulness of fighting coal mine fire with inert gases. A review is made of existing applications that indicate that inert gas methods of fighting mine fires are routine in Czechoslovakia and the U.S.S.R. Details are given of the calculation of inert gas requirements. If sudden ventilation changes can be ...

Abstract. Forest fire is one of the natural calamities. The impact of fire on forest soil depends on its intensity and it also affects soil fertility, nutrients, and properties of soil like texture, color, and moisture content. Fire is beneficial and dangerous for soil nutrients based on its strength and it's duration.
