一建国以来,随着冶金工业恢复和发展,冶金企业的安全技术、劳动保护、工业卫生工作从无到有,逐步发展,日益加强。矿井通风方面:许多矿山在调整、改造通风系统方面做了大量工作,并在院校、科研单位的协作下,提出了一系列适应我国冶金矿山特点的技术措施,创造了一些行之有效的通风网路结构,如棋盘式、梳式、上下行间隔式等。近几年来,电子计算机在通风网路稳定性分析中的应用,从理论上提高了对网路结构合理性的认识。无底柱分段崩落法的采场通风、伴
Since the founding of the People’s Republic of China, with the restoration and development of the metallurgical industry, the safety technology, labor protection and industrial hygiene work of the metallurgical enterprises have grown from scratch and are gradually being strengthened. Mine Ventilation: Many mines have done a great deal of work in adjusting and reforming the ventilation system. With the cooperation of universities and research institutes, a series of technical measures to adapt to the characteristics of China’s metallurgical mines have been put forward and some effective ventilation has been created Network structure, such as checkerboard, comb, up and down interval and so on. In recent years, the application of electronic computer in the analysis of ventilation network stability has theoretically improved the understanding of network structure rationality. Pillarless caving method of stope ventilation, with
