As ore mines ramp up and come on stream, the total number of active surface machines (including trucks, excavators, shovels, loaders, graders and dozers) is forecast to rise from 141,470 in 2020 to 167,367 by 2025. This will be a CAGR of 3.4% from 2020 to 2025. The largest contributor to this growth is expected to be trucks, particularly smaller-sized trucks with shorter lifespans, used extensively in parts of Asia Pacific. Underground mining equipment is similarly expected to see a CAGR of 2.3% in this same time frame, with the number of mining trucks and loaders/LHDs in active underground mines expected to rise to 19,853 by 2025. GlobalData’s extensive mine-site research and equipment models have been used to build a complete view of mobile mining equipment populations globally for trucks, loaders, graders, dozers, excavators and shovels. This report includes informative breakdowns by each major region and key mining country, and also by major commodity.

The new framework has a forecast value of £72m, and covers all major civil engineering works needed to ready treatment sites for the construction of new schemes. These treatment schemes consist of various measures and components, including reed beds, pumping equipment, settlement lagoons and cascade steps.

The four-year framework covers the Coal Authority’s work across England, Scotland and Wales, and contributes to the UK government’s 25-year environment plan.

The Coal Authority said that mechanical and electrical works or other minor works can also be called off the framework to refurbish the Coal Authority’s existing portfolio of more than 82 mine water treatment schemes.

“We’re committed to making a better future for people and the environment in mining areas and a key part of our environmental protection activities is treating water from historical mines to prevent pollution,” Coal Authority operations director Carl Banton said.

The Coal Authority said it had received interest from 60 organisations during the procurement process, and has appointed nine suppliers from those organisations that applied.

Banton added: “This crucial work, funded by the Department for Business, Energy and Industrial Strategy, already sees us treat 122 billion litres of water every year to improve our rivers and protect aquifers and ground waters. We’ll now see that figure increase when more new mine water treatment schemes are built.”

The Coal Authority’s work in treating mine water from historical mines is an important aspect of its environmental protection work. When coal mines close, the pumps that were used to keep water out of the mines are removed, and over time the water levels recover, picking up naturally occurring minerals from rocks such as iron. This can coat riverbeds and prevent plant growth, harming the ecosystems around historical mines.
