  • NSW Mining Methods NSW Mining

    This method is also used to mine metallic minerals like gold and copper. The two main types of underground mining in NSW are bord-and-pillar and longwall mining. Bord-and-pillar: Bord-and-pillar, or room-and-pillar, is the oldest underground mining technique and was common in NSW before longwall mining began in the 1960s.

  • A Brief Introduction to the Types of Surface

    These surface mining methods are considered to be more efficient and economical in extracting minerals as compared to most methods of underground mining. In fact, it can extract almost 90% of ore from a deposit. For this reason, surface mining is the most widely used method in North America.

    Surface mining methods include area, contour, highwall and mountaintop removal. Area mines are surface mines that remove shallow coal over a broad area where the land is fairly flat. After the coal has been removed, the overburden is placed back into the pit. Contour mines are surface mines that mine coal in steep, hilly or mountainous terrain.


    The refraction method has been used in mineral investigations to map low-velocity alluvial deposits such as those that may contain gold, tin, or sand and gravel. Applications in geoenvironmental work include studying the structure, thickness, and hydrology of tailings and extent of acid mine drainage around mineral deposits (Dave and others, 1986).
