Vibration Ore Pass Well The Design Of Expert Systems Research

Vibrating ore-drawing technology is an effective, economic, and safe mining technology. It has made millions of Yuan for economy construction in our country's mines. Vibrating ore-drawing technology is applied in the shaft, which has mended the condition of the draw point, has lightened the labor intension of workers, and has greatly reduced the bottom's blockage in the shaft. But it's also proved that the blockage will not disappear absolutely after the vibrating ore-drawing feeder was applied. This is because the ore's characteristic is short of full consideration. The thesis focuses on the design of expert system for vibrating ore-drawing shaft. It has studied the ore's characteristics that influence the design of vibrating ore-drawing shaft. And it has combined the expert system, database technology and CAD technology to design the expert system for vibrating ore-drawing shaft. The main contents of the research are summarized as follows:The factors, which influence the fluidity of the cracked ores in shaft, are systemically analysed. The ore's characteristics are the fundamental factors that influence the fluidity of cracked ores. While, the shape, parameter, kinetic mode of the shaft can be chosen and adjusted according the ore's characteristics.The coefficient of cracked ore's fluidity Kf is brought forward for the first time. Aiming at that the fluidity of cracked ores is influenced by moisture content, boulder frequency, grain size distribution, lump size, percentage of porosity, cohesion, powder content of powder ore, etc, The coefficient of cracked ore's fluidity Kf is brought forward. And the weight of each influence factor is calculated using the association analysis of gray theory, by which, the error that shorted of consideration of the ore's characteristics in the traditional design is eliminated. At the same time, it has amended three main parameters that are involved in the design of the vibrating ore-drawing shaft, including the cross dimension of shaft, the minimal height of the shaft's bottom, the brow's height of the feeder, using the coefficient of cracked ore's fluidity.The expert system for vibrating ore-drawing shaft is designed using computer. It is divided into two subbases, the design of shaft's structure and the choice of the vibrating ore-drawing feeder's parameters. According to the characteristic of the repository, the repository of vibrating ore-drawing shaft is managed by relation database. The combination of database and expert system is weak coupling in system coupling. The expert system is also combined with the ripe CAD technology of AUTOCAD, and achieves the function of automatically draw.The expert system for vibrating ore-drawing shaft has achieved the intelligently design of vibrating ore-drawing shaft. It not only can design the shaft and choose the parameters of the feeder, but also can offer expert consultation for the arching, blockage and running of ores in the shaft. As well as, the system can offer references for the design of material hopper, chute and other vibrating equipment. The implement of expert system for vibrating ore-drawing shaft will increase the speed and exactness of the design of the vibrating ore-drawing shaft. And it will greatly save the manpower, material resources of the designer. It has great engineering meaning.
