煤矿隔抑爆技术研究现状及发展趋势

摘要

瓦斯煤尘爆炸事故是煤矿安全生产的重大威胁，隔抑爆技术可以有效预防和控制煤矿瓦斯煤尘爆炸事故，能将已发生的爆炸控制在一定范围内，减少事故损失。分析了目前被动式和主动式隔抑爆技术的原理，阐述了世界上主要产煤国在隔抑爆技术及装备方面的研究现状。在此基础上，指出了该领域未来的发展趋势。%Gas and coal dust explosion accident is a major threat to the safe production in coal mines. The explosion suppression technology can effectively prevent the gas and coal dust explosion accident in the coal mine, control the occurred explosion within a certain range, and reduce the accident losses. This paper analyzed the principle of both the passive and active explosion suppression technologies, expounded the research status of the explosion suppression technologies and equipments in some major coal-producing countries in the world. On this basis, the paper pointed out the future development trend of this field.
