Research on Simulation Technology of Automatic Control in Thin Coal Seam Working Face

薄煤层工作面设备稳定性直接关系到整个自动化系统的稳定运行,不仅受外部薄煤层采面煤岩的影响,还与薄煤层三机的协同工作过程密切相关。各设备的稳定运行是保证自动化准确实施的前提,因此以工作面设备自动化控制技术为控制模型,利用Solid Works进行建模,将建立好的采煤机、液压支架和刮板输送机三维模型导入ADAMS中进行仿真分析,验证各项控制技术在薄煤层工况下的适应性。研究表明,薄煤层液压支架满足降-移-升控制过程要求的精确度和适应性要求,刮板输送机推移过程碰撞减少、速度稳定,能够满足薄煤层工作面自动化控制要求,有效解决薄煤层工作面自动化水平不高的问题。

The stability of thin coal seam working face equipment is directly related to the stable operation of the entire automation system. It is not only affected by the external thin coal seam mining rock, but also closely related to the cooperative working process of the coal seam three machines. The stable operation of each equipment is the prerequisite to ensure the accurate implementation of automation. Therefore, the control model was based on the automation control technology of working face equipment, and the model was built by Solid Works, the established three-dimensional models of shearer, hydraulic support and scraper conveyor were introduced into ADAMS for simulation analysis,the adaptability of each control technology under thin coal seam conditions was verified. The research shows that the thin coal seam hydraulic support meets the accuracy and adaptability requirements of the fall-shift-lift control process. The collision of the scraper conveyor during the process is reduced and the speed is stable. It can meet the automatic control requirements of the thin coal seam working face and effectively solve the problem of low automation level of thin coal seam working face.
