带式输送机小半径转弯装置在煤矿运输中的应用

Application of Small Radius Turning Device of Belt Conveyor in Coal Mine Transportation

为了简化系统环节,降低运行成本,提高运输系统的稳定性和生产效率,以鹤煤八矿143胶带上山主运输系统为例,提出小曲率半径转弯装置运输与传统皮带搭接运输两种解决方案。并从运输效率、经济效益及优缺点等方面进行对比分析,最终确定采用小曲率半径转弯装置作为143胶带上山主运输转弯方式,并运用理论计算法对此运输系统的带式输送机进行了选型设计。结果表明,143胶带上山主运输系统采用小曲率半径转弯装置变向转弯输送,提升了煤矿主运输系统的运输效率,改善了运输系统的可靠性,后期运营维护成本降低10%,故障点少,降低了生产成本,每年为企业创造经济效益约500万元。

In order to simplify the system links,reduce the operation cost and improve the stability and production efficiency of the transportation system,taking the 143 belt up the mountain main transportation system of Hemei No.8 Coal Mine as an example,two solutions of small curvature radius turning device transportation and traditional belt lap transportation are put forward.Through the comparative analysis of transportation efficiency,economic benefits,advantages and disadvantages,it is finally determined to use the small curvature radius turning device as the main transportation turning mode of 143 belt up the mountain,and the theoretical calculation method is used to select and design the belt conveyor of the transportation system.The results show that the main transportation system of 143 belt up the mountain adopts the turning device with small curvature radius to change to turning transportation,which improves the transportation efficiency of the main transportation system of the coal mine and improves the reliability of the transportation system.In the later stage,the operation and maintenance cost is reduced by 10%,the number of fault points is less,the production cost is reduced,and the economic benefit for the enterprise is about 5 million yuan every year.
