根据我国西部地区大型和特大型矿井建设需要,为提高50 t级箕斗装载的自动化、智能化水平,在分析现有装载方式使用情况及存在问题的基础上,提出国内首套50 t煤矿立井装载用板式定量输送机装载的方案,并对工艺流程和整机结构、链轮链条等关键部件可靠性,称重元件配置和计量精度,变频驱动智能调速控制等关键技术进行研究。研究表明,板式定量输送机装载速度连续可调,最大可达1.4 m/s、装载时间不大于40 s,满足50 t级箕斗装载的要求。研究结果为样机试制奠定基础,并为千万吨级安全高效立井开采矿井装载系统设计提供参考。

According to the constuction needs of the large and extra large mine in the western region of china,and in orderto improve the automnation & iteligentlevel of 50 tons skip's loading.based on the existing shaf loading pattemns and usage a loading rogram withthe frt set measuring conveyor was poposed and its keytechnolgies were reseached.such as the whole structre.the key components chain spockets des ign.precision weighing and measuring devices automatic mode witha inteligent speed- regulation system of frequency conversion techncogy and others.The theoretical anaysi showed thatloading speed contioucus operaion and up 0 1.4 mn s,the loading time less than 4 s met the requirements of 50 tons skip's loading.These resuits lad the foundation for the prototyp tral and provided referenoe for the shaft loading system design of ten- million ton level mine.
