1 前言长期以来,我局的采煤机械化程度比较低,普通机械化采煤一直上不去,徘徊在25％左右,主要原因是我局破碎顶板所占比重大、小断层多、火成岩侵蚀严重,严重影响机械化采煤的发展。这一重大技术难题,原国家经委确定在“七五”期间委托淮北矿务局全面负责与煤科总院北京开采所、合肥煤研所以及西安煤机厂等单位协作,组织进行攻关研究。 1989年6月,MXP-240采煤机及其配套装备等工艺在我局朱庄矿正式进行工业性试
1 Foreword For a long time, Bureau of Coal Mining mechanization is relatively low, ordinary mechanized mining has been on the rise, hovering around 25%, mainly due to the Bureau of the Bureau of the proportion of broken roof, small faults, severe igneous rock erosion, Seriously affect the development of mechanized coal mining. This major technical problem, the former State Economic Commission decided in the “Seventh Five-Year” period commissioned by the Huaibei Mining Bureau is fully responsible for the coal mining and Beijing Institute of Mining, Hefei Coal Research Institute and Xi’an Coal Mining Factory and other units to organize research. In 1989 June, MXP-240 shearer and its supporting equipment and other technology in Zhuzhuang mine formally conducted an industrial test
