Thin Coal Seam Fully Mechanized Equipment Relability Modeling And Analysis

With thick coal seam in fewer and fewer resources for thin coal seam mining is becoming more and more attention in our country, the development and the development of thin coal seam fully mechanized equipment also become the research focus of some coal mining machinery enterprises in our country, and have a bigger development. But because of thin coal seam mining space is narrow, poor working conditions, the labor intensity of workers, maintenance and equipment movement difficulty making thin coal seam fully mechanized equipment design difficulty and the requirement of reliability to is bigger than the difficulty of other coal seam fully mechanized equipment reliability is higher; And the geologic structure characteristics of thin coal seam of fully mechanized equipment machine power, adaptability, more demanding. At the same time, fully mechanized equipment reliability level not only affect the mine high yield and benefit and influence to the mine safety production. As a result, the reliability of the thin coal seam fully mechanized equipment research is very necessary. This topic main equipment for reliability analysis of full-mechanized mining in thin and it is people, machine, environment impact analysis, through to the shanxi LuAn group DongCheng coal co., LTD., operation research of fully mechanized working face, analysis of actual production data, using the basic theory of reliability, man-machine engineering, fuzzy mathematics and the relevant software was carried out on the thin coal seam fully mechanized equipment reliability modeling, and then find out the weak link of the equipment after analysis and unfavorable factors, thus targeted to improve, to improve the utilization rate of fully mechanized equipment and system effective degree of each link, reduce the number of equipment failure and repair time, improve the reliability of the fully mechanized production system, so as to improve the economic benefits.
