近期我国煤矿采掘设备研制的特点是:努力攻克难采煤层条件下使用的综采成套设备,着重提高采煤设备的可靠性,研制适应多种地质条件的新架型,电机与电气类课题数量增加,并完成了一批监测装置和理论研究课题。一、综采成套设备“七五”国家重点科技攻关项目4.5m厚“三软”煤层一次采全高综采成套设备与工艺已通过鉴定。该项目由徐州矿务局负责,北京开采所、西安、张家口煤机厂参加,在徐州局权台矿进行工业性试验,经受了各种恶劣条件的考验,达了到月产4.2万t的目标。与同类 Recent development of China’s coal mining equipment is characterized by: efforts to overcome difficulties in mining conditions used in fully mechanized coal mining equipment, focusing on improving the reliability of coal mining equipment, development of a variety of geological conditions to develop a new type of frame, electrical and electrical issues The number increased, and completed a number of monitoring devices and theoretical research topics. I. Complete set of equipment and technology of fully-mechanized fully-mechanized mining with 4.5m thick “three-soft” coal seam in the “Seventh Five-year” national key scientific and technological project of fully mechanized mining equipment has passed the appraisal. The project is responsible for the Xuzhou Mining Bureau, the Beijing Mining Institute, Xi’an, Zhangjiakou Coal Machine Factory to participate in the industrial test in Xuzhou Bureau of Taiwan mine, has undergone various harsh conditions of the test, reached a monthly output of 42,000 t aims.
