摘 要 煤炭是我国主体能源，是能源安全的基石，摸清煤炭的资源储量，评价煤炭资源储量开发利用前景，有利于我国煤炭工业规划的制定，有利于煤炭资源节约保护和合理开发利用。随着煤炭工业的现代化，综采工作面机械化程度越来越高，综采工作面机电设备容量不断增大，机械化程度的提高，为加快工作面的推进速度，提高生产率，对煤矿电气设备有了更高的要求，同时煤矿运行的生命线就是电。本次设计主要是为内蒙古呼伦贝尔市扎赉诺尔区灵露矿进行井下综采工作面设备选型和供电设计，设备选型以主要设备为主，通过选型负荷来确定井下供电系统，合理的选型不仅为工矿安全打下了结实的基础，而且在经济效益上也有显著提升。关键词： 采煤机 刮板输送机 负荷统计 变压器 整定保护 AbstractCoal 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 ...
