ABSTRACT
The deeply inclined seams are defined by the coal seams which pitch are between 35∼55° (Wu et al. 2000). Their reserves account for 14% of total coal reserves in China. More than 50% of the mining coal seams in west are the deeply inclined seams mainly distributed in the Sichuan, Xinjiang, Gansu, Fujian, Guangdong, Inner Mongolia and northeast provinces (regions). The deeply inclined seams are difficult mining for low mining production efficiency, bad safety benefits and harsh operating environment (Zhang et al. 2010). So the major coal producing countries exploit hardly these kind seams. Only a few countries are small-scale mining for experimental study. The technology of fully mechanized coal mining of the deeply inclined seams has been obtained success in different degree in China. But there are still some questions about spontaneous combustion prevention and control, which need deeply research and practical explore (Li 2006, Zhang 2009).
