随着煤矿生产向着大型化、高产、高效方向的发展,矿井提升运输等生产环节相互配套,需要配套发展。副井安全门是重要安全设施,其工作的安全可靠性直接影响到提升安全和员工的劳动强度。笔者针对安全门存在的问题,进行结构设计和技术改进。1存在的问题矿用安全门自从在我国生产应用以来,不断进行技术改造,其各项技术性能指标均不断提高,同时也出现了部分结构不适应生产的情况。煤矿副井普遍使
With the development of coal mines towards large-scale, high-yield and high efficiency, the production links such as mine hoisting and transportation are mutually supporting and need supporting development. The auxiliary well safety gate is an important safety device. The safety and reliability of its work directly affects the safety and staff’s labor intensity. I aimed at the security gate problems, structural design and technical improvements. 1 existing problems Since the mine safety gate in China since the production and application, continuous technical transformation, the technical performance indicators are continuously improved, but also appeared in some structures not suited to the production situation. Auxiliary coal mines generally make
