文章提出了22°以上斜井双串车提升井筒下部安装对称岔的不合理性,而把对称岔移至井筒和井底车场交汇处的井底车场的水平面上,既避免了提升矿车在井筒中掉道,又解决了井筒和井底车场连接处钢丝绳拉顶的问题。也为大中型矿井在大倾角井筒内布置双钩串车下料提矸,进行井筒施工,铺设轨道,设计井底车场积累了一定的经验。 The article puts forward the unreasonableness of symmetrical forklifts installed in the lower part of the shaft of a shaft above 22 ° while shifting the symmetrical fork to the level of the shaft bottom yard at the intersection of the wellbore and the shaft bottom yard, Out of the wellbore, but also solve the wellbore and bottom of the car at the junction of steel wire rope pulling the top of the problem. Also for large and medium-sized mines in the large angle of the wellbore layout of the double hook string car dumped refuse, the wellbore construction, laying the track, the design of underground parking has accumulated some experience.
