Working face support - rock protection system software design

According to operate; and object-oriented method is by sending messages to this end, the message is used to stimulate the number of mines are part of the pressure and saliva pull Dong Li 1997. Ng3 - 4.5g. According to the method, a message can inspire depends on the function of an object in one. Only one object of the method to its internal state, and only one way to send a message through the object can be excited. Style from the perspective of software development, object-oriented software development process as a set of the collection of objects interacting, Cheng Yu-design is the definition of the object, the establishment of communication between objects,[link widoczny dla zalogowanych], this method is a basic bottom-up by the demeanor, which is different from the traditional top-down functional decomposition of white software development based on object-oriented thinking style 3 Intelligent Software Design ... Portland limonene layer baskets for Wang Zhu. Reactor for monitoring roof top f {potato Mu ... monitoring Die: port type, the dialog class, graphics class, print, etc. constitute the software directly to the top of the overall role of monitoring Ligusticum I fine I paste a row of ancient stick Miangao s ... ... ... called the angle of a roof for the monitoring role of principal on the roof of the role ll Artemisia monitoring data into the analysis, then the use of mathematical analysis to identify key mechanical factors 【! day advance degrees (1) The overall design intuitive nature (in accordance with the bracket a rock all the components of the system partition) to grasp and easy to understand the design at any time to grasp the direction and goals. (2) has a good scalability, ease of incremental program design. When the working face of a rock support system in the new circumstances may extend the software without affecting the overall performance of the software. (3) has a strong maintainability. Object-oriented technology to achieve the package, an object is an independent unit of data and functions,[link widoczny dla zalogowanych], the user can see only the external characteristics of the object, the system through the windows, menus, dialog boxes, and user interaction, as the object is to achieve its function is hidden within the object, which is a benefit, that is, if you want to further improve the function of the object or modify the implementation details, are confined to the object inside, not to spread, easy to locate the error, so the software can be greatly improved maintenance. (4) output standardization and dynamic. According to the Ministry of Coal Working Face monitoring standard management requirements, the software outputs a table the last two images (face state diagram, face support and resistance distribution of statements), you can also export some other necessary information,[link widoczny dla zalogowanych], such as the operation rate state diagram , station distribution, support failure detection feature reports. Take full advantage of the power of software configuration environment support, Three-dimensional dynamic graphics output. References 1 China University of Mining.

The initial position of top coal in the coal wall before breaking l3m about the compression and shear failure; maximum shear failure generally occurs in the coal wall before the lore, may be cut or compression tension and shear failure. Tensile shear failure of top coal is about 14m wide area, around the coal wall, respectively lOm and 4m, thick 2. Om, located in the upper top coal, asymmetric basin-like shape. (2) the degree of top coal breaking the significance of primary and secondary factors in order: low-level mining height (mining and caving ratio)> coal drawing> roof control from the> support resistance. (3) To improve the level of increase of top coal caving broken, should follow the increase in mining height (mining and caving ratio), the use of small coal drawing, such as increased control from the top of the order to take appropriate technical measures. (4) coal seam 3 of ancient ore mining optimized processing parameters for the control of the top distance of 6m, mining and caving than 11 (ie the underlying mining height 3 ~ 35m, caving is about the thickness of 3-Om), coal drawing 0-6 ~ 0.8m (knife a release), suitable for long shelf-type roof beam type, The point of distance to the coal wall ≥ 4. Om, reasonable working resistance for the 5500 ~ 600okN / rear rack put coal caving support. References 1 Qian Ming higher pressure and control of mining Pina.
