煤矿机电设备选型设计详解.doc

摘要 近年来，煤炭行业存在的矿井规模小、安全水平低、资源浪费严重等问题，对促进矿井生产效率的提高和安全作业，无疑具有极其重大的影响。 ABSTRACT In recent years, the existence of the mine the coal industry for small, safe low level of serious waste of resources and other issues, how to improve mine mechanization as the key to solving this problem. To achieve high efficiency of coal mining, must be the correct selection of equipment. This issue focuses on electrical and mechanical equipment supporting mine to mine mechanical and electrical equipment on the rational selection and design, mine production system to achieve safe, high yield, high efficiency requirements. Overview of the subject in the understanding of mine, based on research equipment mechanized mining face, the central drainage system, ventilation equipment, transportation and upgrading of equipment selection and design. Internship through the screening process the raw data collected, arranged, reference to the relevant requirements of the various procedures related equipment determined the specific parameters of the related checking, determine the equipment layout and the relationship between the use of electricity, electronics and other technology to enhance the mechanical and electrical scientific design of control systems. The issue on mine electrical and mechanical equipment selection and maintenance of a reasonable, scientific use of mechanized equipment, the promotion of improved mine productivity and safety of operations, is undoubtedly an extremely significant.
