  • 摘要

    针对平顶山矿区煤层埋深大,地质赋存条件复杂,采场围岩应力高,井下生产区域温度高的难题,结合可视化远程干预控制、井下信息传输技术及液压支架电液控自适应控制技术,以智能化工作面设备集成控制平台为基础,在平煤十矿构建了河南省首套大采长综采成套装备智能生产系统。建立井下井下万兆工业环网和4G无线通信系统,优化升级矿井信息化平台及通讯系统,支撑矿井智能化安全生产高效运营管理;通过采煤机自适应记忆截割和远程集中控制等关键技术的应用,实现了采煤机与支架的协调联动采煤及“可视远程干预遥控,无人化操作”的智能化生产模式;基于惯性导航调直技术,形成“测量—计算—调直”的工作面智能化高精度调直方法,克服了生产设备高精度定位和调直控制的瓶颈;并以智能泵站液压支架自动补液为例,分析工作面液压支架阻力频率分布规律表明:智能化控制系统对煤层赋存条件具有可靠的适应性,确保了液压支架与顶板岩层之间良好的耦合关系和工作面围岩的稳定性,能够满足安全高效生产的要求。


  • Abstract

    In view of the problems of large coal seam burial depth, complex geological occurrence conditions, high stress of surrounding rock and temperature of underground production in Pingdingshan Mining Area, combined with visual remote intervention control, underground information transmission technology and hydraulic support electro-hydraulic control adaptive control technology, in Pingdingshan No.10 coal mine, the first set of intelligent mining system of large mining length integrated mining set was built in Henan Province which was based on the integrated control platform of intelligent chemical equipment.Underground 10 gigabit industrial ring network and 4G wireless communication system were established, mine information platform and communication system, and support mine intelligent safe production and efficient operation management were also optimized and upgraded.Through the application of key technologies such as adaptive memory cutting and remote centralized control of shearer, the intelligent production mode of coordinated linkage mining of shearer and support and “visual remote intervention and remote control, unmanned operation” was realized.Based on the technology of inertial navigation alignment straightening technology, the method of “measurement-calculation-alignment” was formed, which overcame the bottleneck of high-precision positioning and alignment control of production equipment; taking the hydraulic support of intelligent pump station as an example, the analysis of the frequency distribution rule of the hydraulic support resistance in the working face shows that: the intelligent control system has a reliable adaptability to the coal seam occurrence conditions, ensuring a good coupling relationship between the hydraulic support and the roof strata and the stability of the working face surrounding rock, which can meet the requirements of safe and efficient production.
