  • The Actual Difference Between Surface and Underground Mining

    Surface mining is suitable for large, low-grade ore deposits which occur below a thin layer of rock, or alluvial deposits found in sand and riverbeds. Underground mining is used for small, high-grade deposits covered with a thick overburden (soil and rock above the ore), or for deep and sloping deposits. General ProcessSAFETY ANALYSIS OF SURFACE HAULAGE ACCIDENTS,Although surface mining has always experienced lower accident rates than underground mining, and these rates have been generally improving, recent increases, particularly in the number of powered haulage accidents, have caused concern in the mining industry.
