Abstract

Effective dust control after coal mine blasting is vital for air quality and safety. This study integrates pressure ventilation with air amplifiers, evaluating performance via numerical simulation and PIV validation in a three-centered-arch roadway model. Results show air amplifiers boost airflow, accelerate dust dilution, and reduce high-concentration duration. A dynamic mixed-effects model identifies an optimal setup of 30 m placement and 0.5 MPa pressure, balancing rapid settling and minimal resuspension. The findings offer technical guidance for underground coal mine dust mitigation.

空气放大器促进爆破巷道粉尘扩散沉降的研究

煤矿爆破后粉尘的有效控制对空气质量和安全至关重要。本研究将压力通风与空气放大器相结合，通过数值模拟和PIV验证在三中心拱巷道模型中评估其性能。结果表明，空气放大器可以增强气流，加速粉尘稀释，缩短高浓度持续时间。动态混合效应模型确定了30 m放置和0.5 MPa压力的最佳设置，平衡了快速沉降和最小重悬浮。研究结果对煤矿井下降尘具有一定的技术指导意义。

期刊介绍： ChERD aims to be the principal international journal for publication of high quality, original papers in chemical engineering. Papers showing how research results can be used in chemical engineering design, and accounts of experimental or theoretical research work bringing new perspectives to established principles, highlighting unsolved problems or indicating directions for future research, are particularly welcome. Contributions that deal with new developments in plant or processes and that can be given quantitative expression are encouraged. The journal is especially interested in papers that extend the boundaries of traditional chemical engineering.
