综放工作面大倾角皮带运输机研究与应用

根据开滦唐山矿业公司Y486综放工作面顺槽皮带运输机使用情况分析,对Y485工作面顺槽皮带运输机进行改造,找出在煤层赋水大倾角下山条件下影响皮带运输机运行的主要原因：即皮带运输机机头堆胶带撒煤、中部水煤冲击撒煤、重载停车撒煤、电控系统不完善等问题,采用皮带机头加自动涨紧、加大胶带包角、增加盘式制动闸、完善电控系统等措施予以解决,达到减少机电事故,确保皮带运输机正常使用之目的。

Study and Application on Sharp Inclination Belt Conveyer in Fully Mechanized Caving Face

The crossheading belt conveyer used in Tangshan mining branch company Y486 fully mechanized caving is modified after its application analyzing. The main factors that influence the belt conveyer under the steep coal seam water bearing condition such as coal falling bring by the coal pile in head section,coals falling in middle section bring by wet coal shocking,coals falling bring by heavy load parking,electric control system defects are found. The measures such as the belt head with automatic tension,increasing the wrap angle of the tape,additional disc brake are taken to reduce electromechanical faults and ensure the device work normally.
