Development And Application Of Hydralulic Support And Three-Machine Equiped System

The fully mechanized coal mining is the development trend in the 21st century, while the hydraulic support, shearer and scraper conveyor are the cores of the fully mechanized coal mining and the mine production, they are key to mine safety, high yield and high efficiency. The entire mine production efficiency depends heavily on whether the hydraulic support and the "three-machine" is equipped proper or not.The paper introduced the hydraulic support and three-machine lectotype system developed using VB6.0, Microsoft Excel 2003, Word 2003 and AutoCAD2004 with OLE/COM technology on the platform of Windows XP. The system's function can be divided into four parts: the choice of mining and technology, lectotye of hydraulic support, call hydraulic support's draw, and the report of lectotype. The software's user interface is friendly, and the operation is simple. Users could intuitive understand of the hydraulic support and the match of "three-machine".The first three chapters of the paper mainly introduce the rules and formulas of hydraulic support, and briefly introduce the rule and formula of the choice of shearer and scraper conveyor, and briefly introduce the rule of the match of three-machine . "Chapter 4 mainly use the knowledge of the hydraulic support and three-machine lectotype system described, the computer programming technology in order to intelligent selection the hydraulic support, and the existing three-machine database to three-machine lectotype. in the first three chapters .Users can conveniently view the equipment map of hydraulic support and the" three-machine. In addition, based on the characteristics of support, the system could automatically edit the lectotype report to let users understand the conditions of application and performance of every hydraulic.Chapter 5 implements the lectotype intelligent system, which makes choice of lectotype system based on the actual geological conditions of the existing mine. The system is proved reliable, versatile and practicable.Chapter 6 makes conclusion and prospects.The paper is the main part of Three-Machine Equipped Map which is the seventh fascicule of Graduation Design Handbooks for Coal Mining Engineering Majors (eight in all).
