Optimization and Effect Analysis of Coal Seam Water Injection for Dust Control in Fully Mechanized Mining Face

结合具体工程实际,在分析作业面原注水方案应用不足的基础上,有针对性地提出优化改良方案,并从煤体湿润度和粉尘质量浓度两方面对优化方案应用效果做出探究分析。结果表明,优化后的方案实现了对煤尘质量浓度的有效降低,改善了作业面环境。

Combined with the actual engineering practice,based on the analysis of the deficiencies in appling the original water injection scheme on the working face,this paper proposed the optimization and improvement scheme in a targeted manner and analyzed the application effect of the optimization scheme from the aspects of coal wettability and dust mass concentration.The results show that the optimized scheme achieves an effective reduction of coal dust mass concentration and improves the working face environment.
