兖州矿业(集团)公司济宁二号煤矿在3上薄煤层综采工作面实现的总体配套,具有自动化水平高、安全可靠等特点,比同等条件下的工作面效率和效益有大幅度提高,为我国1.2～2.2 m较薄煤层高性能参数的综采设备填补了国内空白。对以往掩护式支架在井下使用过程中出现的问题进行了分析和改进,采用国际先进水平的液压支架参数可视化动态优化设计软件和计算机模拟试验软件系统,并结合我国具体情况研制ZY4000/10/23型掩护式液压支架。综合国内同类型刮
Yanzhou Mining (Group) Company Jining No.2 coal mine in the three thin coal seam fully mechanized face to achieve the overall package, with a high level of automation, safety and reliability than the same conditions, efficiency and efficiency of the face has greatly improved for the China’s 1.2 ~ 2.2 m thin seam high-performance parameters of fully mechanized mining equipment to fill the gap. This paper analyzes and improves the problems that occurred during the downhole operation of the shelves in the past. The internationally advanced hydraulic support parameters are used to visualize the dynamic optimization design software and the computer simulation test software system. Based on the actual situations in China, ZY 4000/10/23 Type cover hydraulic support. Comprehensive domestic scraping the same type
