· In surface mining, the ground covering the coal seam (the overburden) is first removed to expose the coal seam for extraction. The elements of a surface mining operation are (1) topsoil removal and storage for later use, (2) drilling and blasting the strata overlying the coal seam, (3) loading and transporting this fragmented overburden material (called spoil), (4) .
· The cause of fatigue fracture in gearbox housing of coal mining machine cutting part (CPGH) is analyzed in this paper. Considering the effects of lowfrequency external excitation caused by coal cutting and highfrequency internal excitation caused by gear meshing, systematic studies of force analysis and local resonance analysis are employed. Force analysis is .
A sophistied machine called a continuous miner extracts the coal or more conventionally, coal can be blasted from the working face. Underground mining operations leave tailings. Tailings are the residue left over from the process of separating coal from economically unimportant minerals during the coal processing step at plants.
· The Enforcement Directorate (ED) has taken up the investigation of the alleged coal theft at Amrapali Project under Magadh Amrapali Area of the CCL that caused a loss of Rs Crore to the CCL.

Surface Coal Mining Methods in Australia 5 2. Open cut mining methods strip mining Largescale open cut coal mining operations commenced in Australia in mid 1960s and since then there has been significan t developments in this method of mining. The mines are now operating at significantly higher annual tonnages, growing deeper, more complex and
China Coal Energy also conducts coal chemicals production, coal mining equipment manufacturing, pit mouth power generation, and coal mine design businesses. It owns 12 coal mines, 13 coal processing plants, 5 coking plants, 4 coal mining equipment manufacturing plants, and 2 mine design institutes, making it one of the leading coal mining companies in .
· Our company owns many kinds of machines to process coal for different purposes. The current Chinese mining enterprises keep the extensive operation mode for the coal resource, which leads to the intensifiion of the haze problem.
Wirtgen surface miners can cut, crush and directly load material onto trucks or dumpers in a single operation. This saves time and the additional cost of purchasing machinery and fuel. Working with the 4200 SM in the Australian mine resulted in a 79% reduction in fuel consumption per cubic meter of mined material.
