目前,我国煤矿和选煤厂的采、制、化作业的机械化水平还不高,试验的代表性也较差。为了逐步提高选煤厂的机械化、自动化水平,必须对煤质检验和技术检查作业进行现代化改造。本文介绍近年来国内的新技术和先进经验,以及国外的现状和发展趋势,探讨实现煤质检验现代化的途径。一、煤质试验的理论基础煤质试验的理论基础是概率论和数理统计学。它所讨论的是试验过程的随机误
At present, China’s coal mines and coal preparation plants, mining, mechanization of the operation level is not high, the representativeness of the test is also poor. In order to gradually improve the mechanization and automation of the coal preparation plant, the coal quality inspection and technical inspection operations must be modernized. This article introduces the domestic new technologies and advanced experience in recent years, as well as the status quo and development trend of foreign countries to explore ways to achieve the modernization of coal quality inspection. First, the theoretical basis of coal test The theoretical basis of coal quality test is the probability theory and mathematical statistics. What it discusses is the random error of the test process
