The proceedings of the 11th International Mine Ventilation Congress (11th IMVC), is focused on mine ventilation, health and safety and Earth science. The IMVC has become the most influential international mine ventilation event in the world, and has long been a popular forum for ventilation researchers, practitioners, academics, equipment manufacturers and suppliers, consultants and government officials around the globe to explore research results, exchange best practices, and to launch new products for a better and safer industry. It also serves as a useful platform to attract and train future ventilation professionals and mine planning engineers, as well as for mining companies to discover better practices to provide better ventilation planning.
Excerpt from Effects of Moisture on the Spontaneous Heating of Stored Coal There is no doubt a floating opinion among people accustomed to the handling of coal to the effect that moisture does increase the tendency to spontaneous combustion. In a letter to the English commission in 1876, Mr. Poole, inspector of mines, Nova Scotia, makes the following remark: Heat has been observed in piles of slack coal that have been accumulated during the winter, when the season has been showery but not when it has been dry. This evidence is very direct and absolutely opposed to Fayol's experience, and a great deal of similar evidence was tendered to the English commission. For instance, out of 26 answers to questions as to the effect of moisture every reply was to the effect that moisture was a source of danger. An examination of the reported evidence shows that in every case (with the above exception) this was a matter of impression merely. Cross-examination of a number of witnesses before the New South Wales commission, who held this opinion, convinced me that it was in general held'on very slender grounds; and two cases in which the rain had apparently increased the tendency of the coal to heat were otherwise explained. In the presence of air and moisture pyrite readily oxidizesc and pyrite in coal has often been blamed for spontaneous combustion. Threlfall d showed that the oxidation of pyrite has much less effect in the heating of coal than the oxidation of the coal substance itself. He reviewed the work of previous investigators and commissions that investigated mine fires all the evidence was against the idea.

This textbook provides students and academics with a conceptual understanding of fire behavior and fire effects on people and ecosystems to support effective integrated fire management. Through case studies, interactive spreadsheets programmed with equations and graphics, and clear explanations, the book provides undergraduate, graduate, and professional readers with a straightforward learning path. The authors draw from years of experience in successfully teaching fundamental concepts and applications, synthesizing cutting-edge science, and applying lessons learned from fire practitioners. We discuss fire as part of environmental and human health. Our process-based, comprehensive, and quantitative approach encompasses combustion and heat transfer, and fire effects on people, plants, soils, and animals in forest, grassland, and woodland ecosystems from around the Earth. Case studies and examples link fundamental concepts to local, landscape, and global fire implications, including social-ecological systems. Globally, fire science and integrated fire management have made major strides in the last few decades. Society faces numerous fire-related challenges, including the increasing occurrence of large fires that threaten people and property, smoke that poses a health hazard, and lengthening fire seasons worldwide. Fires are useful to suppress fires, conserve wildlife and habitat, enhance livestock grazing, manage fuels, and in ecological restoration. Understanding fire science is critical to forecasting the implication of global change for fires and their effects. Increasing the positive effects of fire (fuels reduction, enhanced habitat for many plants and animals, ecosystem services increased) while reducing the negative impacts of fires (loss of human lives, smoke and carbon emissions that threaten health, etc.) is part of making fires good servants rather than bad masters.
