ELMB型12m~2断面液压传动煤巷掘进机及配套的SJ-1型皮带转载机是我国“六五”期间国家技术攻关项目。主机由上海煤矿机械研究所设计、南京晨光机械广制造;转载机由上海煤矿机械研究所设计、浙江桐乡煤机厂制造。86年1月31日至2月2日在徐州矿务局通过了由煤炭部技术发展司和煤炭部科学院组织的技术鉴定。样机从1985年10月1日到12月底止,在徐州矿务局庞庄矿东城井进行了工业性试验。巷道断面为8.32m~2、坡度为±2°,连续工作三个月共掘巷道1184m,其中半煤岩巷道占237m。11月进尺达503m。达到了设计要求。
ELMB 12m ~ 2 section of hydraulic transmission coal tunneling machine and supporting SJ-1-type belt loader is China’s “Six-Five” period of national technology research projects. Host by the Shanghai Institute of Coal Mine Machinery Design, Nanjing Chenguang Guang Machinery Manufacturing; reproduced by the Shanghai Coal Mine Machinery Institute, Zhejiang Tongxiang Coal Factory manufacturing. January 31, 2006 to February 2 in Xuzhou Mining Bureau adopted by the Ministry of Coal Technology Development and the Ministry of Coal Science and Technology Organization of the technical appraisal. Prototype from October 1, 1985 to the end of December, in Xuzhou Mining Bureau Pangzhuang mine Dongcheng well conducted an industrial test. The section of the roadway is 8.32m ~ 2, the slope is ± 2 °, and the roadway is 1184m in continuous work for three months, of which the semi-coal and rock roadway accounts for 237m. In November into the level of 503m. Reached the design requirements.
