我国煤矿硫化氢成因及防治对策

Origin and countermeasures of hydrogen sulfide in coal mines in China

分析国内外相关成果,对硫化氢成因、判识及防治对策进行述评,发现通过硫同位素值、形态硫含量、硫化氢浓度、煤层埋藏温度和深度等指标可以判识硫化氢来源。论述了个体防护法、化学中和法和通风改进法等煤矿硫化氢主动、被动综合治理技术,指出了煤矿硫化氢防治技术方面存在的不足,提出了应加大研制硫化氢吸收液新材料,构建智能化、全方位、多区域硫化氢综合监测、检测和防治技术体系,实现煤矿硫化氢防治技术安全、经济、环保和可持续。

Based on the analysis of relevant achievements at home and abroad,the causes,identification methods and countermeasures of hydrogen sulfide are reviewed.It is found that the source of hydrogen sulfide can be identified by indicators such as sulfur isotope value,morphological sulfur content,hydrogen sulfide concentration,coal seam burial temperature and depth.The technologies of active and passive comprehensive treatment of hydrogen sulfide in coal mines,such as individual protection method,chemical neutralization method and ventilation improvement method,are discussed.This paper points out the shortcomings in the prevention and control of hydrogen sulfide in coal mines,and puts forward that the development of new materials for hydrogen sulfide absorption liquid should be increased,and an intelligent,all-round and multi-regional hydrogen sulfide comprehensive monitoring,detection and prevention technology system should be established to realize the safety,economy,environmental protection and sustainability of hydrogen sulfide prevention and control in coal mines.
