  • The complete guide on web crawling techniques

    The incremental crawler gradually refreshes the existing collection of pages by visiting them frequently. It does so based on the estimate of how often the pages change. It also exchanges less important pages by new and more important pages. It also resolves the problem of content consistency. The benefit of an incremental crawler is that only the valuable data is provided to the user. Thus

  • Health Hazards of Mining and Quarrying ILO Encyclopaedia

    The most common processes that produce respirable silica dust in mining and quarrying are drilling, blasting and cutting silica-containing rock. Most holes drilled for blasting are done with an air powered percussion drill mounted on a tractor crawler. The hole is made with a combination of rotation, impact and thrust of the drill bit. As the hole deepens, steel drill rods are added to connect

  • Differences Between a Dozer and a Loader Difference

    A dozer is a versatile piece of equipment which is often used in quarrying areas, mine sites, heavy industry factories, military bases, farms, or any other engineering projects that entail its use. Basically, it is a crawler equipment which is used to push a large quantity of soil, rubble, sand, and any earth material. It is used to particularly move aside quantities of earth which often dumps
