Failure analysis of scraper conveyor based on fault tree and
The scraper conveyor is an important equipment in modern coal mining process. Traditional alloy steel scrapers, as one of the main components of the scraper conveyor, are disadvantageous in that they are not only vulnerable to failures such as fracture and wear, but also take up over 35% of the output power to rotate themselves, The belt conveyor is a continuous conveying equipment which is composed of conveyor belts connecting various parts scattered and installed in a certain position. The length of a belt conveyor can reach dozens of kilometers. The belt conveyor is generally composed of conveyor belt, idler, roller, transmission device, tensioning device, Belt Conveyor, Classification of SpringerLink

Conveyor Mechanical Devices for Automation & Efficiency
conveyor, any of various devices that provide mechanized movement of material, as in a factory; they are used principally in industrial applications but also on large farms, in warehousing and freight-handling, and in movement of raw materials. Conveyors may be only a few inches in length, or they may be integrated systems several miles long.The belt conveyor is the most commonly used conveying equipment in the coal mining industry. As the core part of the conveyor, the belt is vulnerable to various failures, such as scratches, cracks, wear and tear. Inspection and defect detection is essential for conveyor belts, both in academic research and industrial applications. In this Belt Tear Detection for Coal Mining Conveyors MDPI

Green coal mining technique integrating mining-dressing-gas
The Ji 15 coal seam of the mine is highly gassy, has low permeability, and does not have a protective seam, which is the requisite condition for conventional mining. This study proposes a coal mining technique that integrates the processes of mining-dressing-gas draining-backfilling-mining (MDGBM) to address the previously mentioned strong transmission capacity and works continuously [1,2]. The composition of a coal mine belt conveyor is shown in Figure1; it mainly includes a driving motor, a belt, a transmission device, a tensioning device, a driving roller and an idler. The efficiency of coal mine transportation is directly related to the belt conveyor. Most of theFault Diagnosis of Permanent Magnet Synchronous
