Coal is the main energy in China, is the cornerstone of energy security, find out the coal resources reserves, the exploitation and utilization of coal resources and reserves evaluation of prospects, conducive to the development of China's coal industry planning, is beneficial to saving the protection and rational development and utilization of coal resources. With the modernization of the industry, fully mechanized working face of increasingly high degree of mechanization, capacity of electromechanical equipment in fully mechanized mining face is increasing, the degree of mechanization raise, to speed up the working face advancing speed, improve the productivity, there are more requirements on the coal mine electrical equipment, at the same time the lifeline of run of mine coal is electric. This design is mainly for the Inner Mongolia Hulun Buir City District of Zhalainuoer dew mine fully mechanized mining face underground equipment selection and power supply design, selection of equipment to the main equipment, to determine the underground power supply system through the selection of load, the reasonable selection for the industrial and mining safety not only laid a solid foundation, but also a significant increase in economic benefit.
