KGU5B矿用超声物位仪在井下煤仓中的应用

摘要

Providing raw coal stored material transportation of three blasting mining face,688 coal bunker,684 coal bunker,65 coal bunker and surge coal bunker are raw coal bunker used underground in Baishan Colliery.With the improvement of raw coal transportation automation in China,all kinds of parameters for raw coal transportation have higher requirements in recent years in Baishan Colliery,especially the accuracy of material level of underground stored material coal bunker.After long-term using,the factor such as complex internal structure of shaft stored material coal bunker,different traditional feed-in method of coal bunker,different feed-in method for belt conveyor and scraper conveyor,different measured medium,specific gravity and granularity,etc.,brings great difficulty to measuring.Selected to use in 2009,KGU5B Mining Ultrasonic Level Instrument has been reliably used in the measuring of solid particle and bulk material and has been recognized,which has played an irreplaceable role in coal bunker level and controlling crushed lump coal,etc..%百善煤矿现井下使用的原煤煤仓有688煤仓、684煤仓、65煤仓、缓冲煤仓,提供三个炮采面的原煤运输贮料任务。随着我国原煤运输自动化的不断提高,百善煤矿原煤运输对于各类参数近几年以来有了更高的要求,尤其是井下贮料煤仓料位的准确性,要求比以往更加严格。井下贮料煤仓经过长期使用,内部结构相对复杂,再加上传统的煤仓进料方式又有所不同,其中皮带输送机进料、刮板运输机进料方式的不同,及被测介质也各不相同,比重,颗粒度等给测量带来很大困难。在2009年度选型投入使用的KGU5B矿用超声物位仪在固体颗粒和块状物料的测量中已经被可靠采用,并且得到了认可,在煤仓煤位、控制块煤破碎等方面发挥了不可替代的作用。
