avolouhintamenetelmillä

Avolouhintamenetelmillä refers to open pit mining methods. This is a surface mining technique where minerals or aggregates are extracted from an open pit. This method is typically used when ore deposits are close to the surface and relatively large. The process involves excavating the material in a series of steps, creating benches or terraces that step down into the earth.

The key steps in avolouhintamenetelmillä include drilling blast holes, charging them with explosives, and then detonating the explosives to break up the rock. The broken rock, known as muck, is then loaded onto trucks or conveyor systems by excavators or shovels. These vehicles transport the material to crushing and processing facilities. The waste material, or overburden, is removed to expose the ore body.

Avolouhintamenetelmillä is characterized by its large scale and the significant visual impact it has on the landscape. Environmental considerations are crucial in the planning and execution of these operations, including dust control, water management, and eventual mine reclamation. Safety is also paramount, with strict protocols in place for operating heavy machinery and managing explosives. The economic viability of avolouhintamenetelmillä depends on the grade of the ore, the depth of the deposit, and the cost of extraction and processing. It is a common method for mining coal, copper, iron ore, and various types of stone.
