Optimization for Substep Three-dimensional Dust Control System at Fully Mechanized Excavation Face
-
摘要: 基于综掘工作面分步立体式控降尘系统在现场应用中出现的不足之处,对系统中掘进机环形外喷雾装置及通风除尘用吸尘罩的结构进行了优化,并选用了更加简便的调风控尘装置工艺配套方式,在保证了系统原有控降尘效果的同时,极大地提高了系统在井下恶劣作业环境中的适用性及可靠性。Abstract: For the inadequacies of substep three-dimensional dust control system at fully mechanized excavation face, we optimize the structure of annular outer mist spray device and dust cover for heading machine, and select more convenient mode of process matching for dust control devices. All these ensure the original effect of dust control, and greatly improved the applicability and reliability of the system in harsh operating environment of coal mine.
