综掘工作面通风参数优化研究

Study on Optimization of Ventilation Parameters in Fully Mechanized Excavation Face

综掘工作面通风效果良好,对于矿井生产作业安全、高效、持续的开展有重大意义。在分析粉尘危害的基础上,借助ANASYS数值模拟技术,针对压入式和长压短抽式两种通风方法的参数优化开展分析,并分别确定了其通风效果最佳时的参数值,对于提升矿井综掘工作面通风质量,实现综掘工作面粉尘的有效防治具有良好的指导和借鉴意义。

The good ventilation effect of fully mechanized excavation face is of great significance to the safe, efficient and contin-uous development of mine production and operation. On the basis of the analysis of dust hazards, with the help of ANASYS num-erical simulation technology, this paper analyzed the parameter optimization of the two ventilation methods, namely, the compre-ssion type and the long pressure and short suction type, and determined the parameter values when the ventilation effect was the best, which has good guidance and reference significance for improving the ventilation quality of the fully mechanized excavation face of the mine and realizing the effective prevention and control of dust in the fully mechanized excavation face.
