确定采煤参数时,广泛采用局部优化方法。但研究这些方法时,都没有考虑生产和备用工作面相互影响。一个矿井回采工作面总体是一个统一的工艺系统,因而研究这一系统中的各个环节必须考虑其间的相互联系。一个工作面产量增大,将使采区采煤成本降低。在各工艺环节通过能力限定的具体矿井,减少生产工作面数,可能使一个工作面产量暂时地增加,同时将引起各回采工作面整个系统可靠性和生产连续性降
When determining the coal mining parameters, the local optimization method is widely used. However, none of these methods have been studied to consider the interaction between production and backup work surfaces. A mining face is generally a unified process system, so the study of the various aspects of the system must take into account the interrelationships between them. An increase in production of a face will reduce the cost of mining in the mining area. Reducing the number of working faces in a specific mine with limited capacity at all stages of the process may temporarily increase the output of one working face and at the same time will cause the overall system reliability and production continuity of each working face
