Page 725 dragline at Turkish Coal Association Yenikoy Open Pit Coal Mine, Milas. A dragline excavator is a piece of heavy equipment used in civil engineering and surface mining . Draglines fall into two broad categories: those that are based on standard, lifting cranes, and the heavy units which have to be built onsite.
Open cast mining in the today's world has cyclic reappearance with prominent role in to mining sphere. Nowadays the extent of mineral own by open cast mining is increases from year to year. This is due to the rapid strides made in the field of manufacture of open pit machinery. There has been a design explosion in the field of machinery, which have grown into enormous sizes with production ...

Coal Mining. Print. Coal is a solid that, if we are to use it, must be extracted from the earth. This is coal mining, going into the earth to remove coal for our consumption. The basic steps of mining and processing coal are described below. There are two general methods of coal mining: surface mining and underground mining.
To start with, a detailed literature survey was carried out in the area of noise pollution and its control in the mining industry, embracing equipment like from Heavy Earth Moving Machinery (HEMM), compressors, workshops, pneumatic drills, processing plants etc., to know the quantum of work done in India and worldwide.
