本文介绍了分区开拓系统的优化内容、准则和方法;提出了分区开拓系统的结构模型;应用最优化理论和价值工程方法,建立了分区开拓系统优化模型;比较系统地阐述了主系统模型的结构、原理,介绍了10个子系统的主要内容和方法。所建立的优化模型和编制的计算机程序适用于近水平和缓倾斜煤层分区开拓系统的综合优化问题,并以山西TL矿井作为实例进行了应用。 In this paper, we introduce the optimization contents, guidelines and methods of partitioning and developing system. We put forward the structural model of partitioning and expanding system. By using optimization theory and value engineering method, we set up the partition and development system optimization model, and systematically expound the structure of the main system model , Principle, introduces the main content of 10 subsystems and methods. The optimized model and computer program are applied to the comprehensive optimization of the open pit system in near-horizontal and gently inclined coal seam. The application of TL mine in Shanxi Province is taken as an example.
