Surface Mining Techniques Surface mining of coal is characterized by the use of large, capital-intensive and effi-cient mining equipment. First, the overlying soil and rock layers (overburden) are re-moved. The coal is then fractured with explo-sives or machines, and loaded onto vehi-cles for haulage from the mine site. Finally,
While underground mining methods show higher cost than open pit, their complexity almost always means that there is opportunity in both productivity and cost improvement.

However, as surface mineral deposits are exhausted, underground mining will inevitably become more prevalent. In addition, as more easily minable deposits are depleted, mining technology and equipment and mining systems for extracting problematic deposits will have to be developed.
Mining Equipment Market Size & Trends. The global mining equipment market size was estimated at USD 141.31 billion in 2023 and is expected to expand at a compounded annual growth rate (CAGR) of 5.2% from 2023 to 2030. Ongoing digital mine innovation is expected to transform the key aspects of mining during the next few years.
The mining fleet is one of the industry's primary sources of on-site greenhouse gas (GHG) emissions. Mobile mining equipment at a surface mine can account for up to 30 percent of on-site GHG emissions—or up to 80 percent if the mine doesn't have contiguous smelting or refinery facilities.
