地面煤堆和矸石山自燃的问题是煤炭开采和储运过程中遇到的诸多难题之一。热棒在无源冷却系统中具有强大的热量传输能力,为防止煤堆(矸石山)因蓄热而导致自燃,提出了使用热棒加快煤堆热量散失速率,破坏蓄热环境,进行深部移热的方法,防止煤堆(矸石山)自燃。重点讨论专用热棒在煤堆自然发火蓄热高温区域移热实践中面临的设计方法、基础参数、性能、实施装备和工艺等方面的技术难题,并给出解决思路。
The spontaneous combustion of coal storage pile and waste dump is one of the unresolved problems encountered in coal mining and transportation. Thermal probe has a powerful heat transfer capability in a cooling system without external energy. In order to prevent spontaneous combustion of coal storage piles(hillock) due to regeneration, a method using thermal probe to remove heat in coal storage pile is proposed, which damages the regeneration environment to prevent coal fire. In this paper, the characteristics of spontaneous combustion of coal pile are analyzed in detail, and the latest applications and research practices of heat pipe in other industries are also included. Compared with other traditional technologies on coal fire prevention, several advantages of heat pipe in coal fire controlling are described. Technical problems of specific thermal probe, design methods, basic parameters, performance,equipment and implementation technology are discussed. And several measurements are given for its application and promotion, which may enrich the technical means of prevention and control in coal spontaneous combustion.
