综合机械化采煤是现代化的生产方法。在综采工作面生产过程中,充分发挥液压支架支护强度(工作阻力)的作用,获得较高的产量,是一个极为重要的问题。正确地分析液压支架支护强度与工作面产量的关系和作出科学的预测,将对生产的发展具有现实的指导意义。在预测中,各局矿的工作面产量统计数字是一个包含有技术、生产条件、管理水平等综合因素的指标。这些条件和水平,各局矿存在着很大的差异,需要对具件条件做具体分析。因此,本文以大同矿务局的统计数据为例来阐述GM(1,1)预
Comprehensive mechanization of coal mining is a modern method of production. In the production process of fully mechanized mining face, giving full play to the role of hydraulic support support strength (work resistance), to obtain higher yield, is an extremely important issue. Correctly analyzing the relationship between the support strength of the hydraulic support and the production of the working face and making a scientific prediction will have realistic guiding significance for the development of production. In the forecast, the output statistics of the working face of various mines and mines is an indicator that includes comprehensive factors such as technology, production conditions and management level. These conditions and levels, Bureau of mine there is a big difference, the need for specific conditions to do specific analysis. Therefore, this article uses the statistics of Datong Mining Bureau as an example to illustrate GM (1,1) pre-production
