Abstract: In order to facilitate hydraulic support type-selection design for coal mine designers, a type-selection design system for hydraulic support based on B/S model was developed by use of C# language, ASP.NET technology, Visual Studio 2013 system development tool and SQL Server 2008 database. Whole design and function realization schemes of the system were introduced. The system can output hydraulic support type-selection results by users inputting design parameters and select the optimal type from the type-selection results. Feasibility of the system is verified through an actual hydraulic support type-selection example of a coal mine.
