近几年来我国无煤柱开采技术在易自燃煤层中开始了试验应用。但这类煤层应用无煤柱开采的许多理论和实际应用问题,目前正处于初始试验研究阶段,尚未得到正确的认识和解决,影响着这一先进开采技术的广泛推广应用。我们在调查全国近30个重点煤矿和搜集有关资料的基础上,对无煤柱开采与自然发火的关系;自然的影响因素;自燃
In recent years, China’s non-pillar mining technology in the spontaneous combustion of coal began in experimental applications. However, many theoretical and practical applications of this type of coal pillar without pillar mining are currently in the initial stage of experimental research and have not yet been correctly recognized and solved, affecting the widespread application of this advanced mining technology. Based on the survey of nearly 30 key coal mines in the country and the collection of relevant data, we analyzed the relationship between non-pillar mining and natural ignition, factors affecting nature, spontaneous combustion
