摘要: 煤仓是煤矿连续运输系统中的关键环节,为提高其使用寿命,减少停产检修时间,通过总结生产实践经验,参考煤仓中煤流研究成果,设计对煤仓下口的仓壁结构和收口位置进行了改进,既提高了其仓壁的抗冲击性能,也解决了煤仓下口被击穿影响装载硐室中设备人员安全的问题。为保证空气炮正常使用,根据仓内煤流流动特性和生产实践经验,设计对空气炮的布置方式和保护方式进行了改进,防止其出口被冲击破坏。通过不断改进完成的若干煤仓设计,经多年使用证实其结构合理,安全可靠,维修周期延长,对于煤仓设计具有指导意义。

Abstract: The coal bunker is the key part of the continuous transportation system of coal mine. In order to improve its service life and reduce the shutdown maintenance time, the wall structure and closing position of the lower entrance of the coal bunker are improved, which not only improves the impact resistance of the wall, but also make sure the safty of workers and equipments when loading room has been brokendown. In order to ensure the normal use of the air gun, according to the flow characteristics of the coal flow in the bin and the production experience, the layout and protection mode of the air gun are improved, and solve the problem that the air gun shutdown when its broken. Through continuous improve design of coal bunker, it has been proved that the structure is reasonable, safe and reliable, and the maintenance period is prolonged after years of use, which has guiding significance for coal bunker design.
