煤矿的井上、井下都有溜煤或临时储装煤用的溜煤眼或煤仓。它是联系各个生产环节的重要枢纽。一旦发生故障,就有可能造成某个工作面或采区甚至全矿的停产。有时堵塞得不严重,可用长柄工具向堵塞处用力捅几下,就可能捅开,迅速恢复生产。但有时堵塞情况严重,处理起来就不那么容易了。 根据现场长期观察分析,煤仓(溜煤眼)堵塞的原因和常发地点,也是有规律可寻的。常见的堵塞现象有:卡堵、结拱、粘壁等。主要是由于进入煤仓(溜煤眼)时超过允许规定范围的大块煤或矸石,相互咬卡;含水份过多的碎煤长期受压沉积;煤仓(溜煤眼)的支护壁衬质量差,受损变形等,均足以使在煤仓(溜煤眼)中的各种物流不畅而出现堵塞现象。堵
Coal mine, downhole have coal or temporary coal storage slip coal or coal warehouse. It is an important hub for all production links. In the event of failure, it is possible to cause a face or mining area and even the whole mine shutdown. Sometimes blockage is not serious, long handle tools can be used to stab the plug a few hard, it may be opened, the rapid resumption of production. But sometimes the blockage is serious and it is not easy to deal with. According to the site long-term observation and analysis, coal bunker (coal-slip eyes) blockage and the frequent occurrence of the site, but also regularly find. Common phenomenon of jamming: jam, knot arch, sticky wall and so on. Mainly due to enter coal bunker (slippery coal) exceeds the allowable range of large pieces of coal or gangue, bite each other; containing too much water crushed coal long-term pressure deposition; coal bunker (slip coal eyes) support wall Lining poor quality, damaged deformation, etc., are sufficient to make the coal warehouse (slippery coal eyes) in a variety of poor logistics and clogging phenomenon. Blocking
