  • Open Cut and Underground Mining iMINCO

    Underground Mining is generally used for areas where the mineral seam is too far underground for open cut mining to be of use. A tunnel called a decline is created to allow workers and machinery to reach the location of the minerals. Stope mining is used for most hard rock mining of minerals such as copper silver lead and zinc. Stopes are large openings or rooms connected by tunnels in

    performed at its closedside setting (CSS). be deducted from the openside setting (OSS) for calculation of the closedside setting (CSS) according to the size of the crusher to be adjusted. Example If the measurement of the OSS in the C160 model is 191mm (7 1/2) then the CSS will be 191 41 = 150 mm (7 1/2 1 5/8 = 5 7/8). By determining the CSS we will know the closed

  • Controlling the risk of dust exposure to workers in mines

    Maintain unmade roads and ensure ground conditions throughout sites are appropriate to the machines using them. Provide training and information to workers on the hazards risks and controls of dusty tasks as well as supervision for workers. Limit the duration and magnitude of exposure to dust (e.g. worker rotation job task changes).

    for the automatic control of the set. The open and closedside sets and the gape are identified in Figure 5.1. The throw of the crusher is the distance that moving jaw moves in going from OSS to CSS. Throw = OSSCSS. The capacity is a function of size and OSS. Manufacturers publish tables of capacity for their crushers of various size as a function of the openside set. 5.1.1 Cone crushers

  • What are the main methods of mining? American

    There are four main mining methods underground open surface (pit) placer and insitu mining. Underground mines are more expensive and are often used to reach deeper deposits. Surface mines are typically used for more shallow and less valuable deposits. Placer mining is used to sift out valuable metals from sediments in river channels beach sands or other environments.

    The widest distance is known as the open side setting (OSS) and the narrowest the closed side setting (CSS). These settings are important. The OSS is the largest distance between the concave and the mantle at the bottom of the crusher so it determines the largest particle size of the outgoing product. As the smallest distance between the concave and the mantle the CSS is the final crushing
