  • Types of Underground Mining Method Comparison

    In any discussion of Methods of Underground Mining Comparison one is repeatedly confronted with the difficulty of dealing with so many variable conditions. It is not an exact science and in the choice of a method each varying factor has a certain weight which in many cases experience alone can determine.

    Mining Methods. There are four key stages of work involved in mining for minerals. These include 3415 3416 Prospecting The purpose of this stage is to identify areas that are likely to contain mineral deposits. The work includes geological geochemical and geophysical surveys (e.g. seismic surveying) aerial surveys including the taking of samples by lowimpact mechanical methods.

  • Digging deeper Mining methods explained Anglo American

    The underground mining methods we use include room and pillar narrow vein stoping and largescale mechanised mining. Room and pillar mining is a style of mining where tunnels are driven in a chess board pattern with massive square pillars between them which are gradually cut away as the work proceeds. We use this for mining coal.

  • 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. Insitu mining
