Mining machinery engineering

<h2 id="history">History</h2> <p>Surface mining equipment evolved at a high pace in the 20th century as the scale of mining grew. In the first twenty years of the 1900s, steam power was largely replaced by <a href="/facts/Internal_combustion_engines/Ju4BXzj0">internal combustion engines</a> and <a href="/facts/Electric_motors/ArD7BGDa">electric motors</a>. Till the 1970s such equipment mainly used mechanical systems and cables for power transmission after which they started to be replaced by <a href="/facts/Hydraulic_drive_system/4GeHHaKb">hydraulic drive system</a> for small machines. However, mechanical and cable drives are still dominant in large machines. A similar development took place in the development of underground machinery. <a href="/facts/Drilling/gdr632GJ">Drilling</a> and <a href="/facts/Rock_blasting/lh38AsAB">blasting</a> replaced manual cutting of ores. Lately, the use of continuous mining machines has become the order of the day to comply with environmental regulations, protect surface features, and also achieve an increased production rate. As the concern for safety in mines increased and highly stringent regulations were put in place, it required mining machinery engineers to be highly conversant with such regulations. </p> <h2 id="employment">Employment</h2> <p>Since Mining Machinery Engineering is a wholesome branch, the course of which covers disciplines like <a href="/facts/Mechanical_Engineering/cbId4fye">Mechanical Engineering</a>, <a href="/facts/Mining_Engineering/VEAosBGK">Mining Engineering</a>, Mineral Engineering, <a href="/facts/Electrical_Engineering/YYXW1KLW">Electrical Engineering</a>, the employment opportunities are tremendous. Mining Machinery Engineering provides excellent career opportunities in various industries such as <a href="/facts/Mining/g6uDIFab">mining</a>, heavy earth moving equipment, <a href="/facts/Construction_industry/58eqDhy9">construction industry</a>, mineral processing, and other related industries. </p> <ul><li><a href="https://www.iitism.ac.in/index.php/mining_Machinery_engineering">Indian Institute of Technology (Indian School of Mines), Dhanbad - Department of Mining Machinery Engineering</a></li></ul>
