Evaluation of the effectiveness of various composite dust suppressants in suppressing coal–rock mixed dust

Key Points

• Effectiveness of composite dust suppressants significantly reduces coal-rock mixed dust emissions, enhancing safety.
• Measuring dust emission reduction, some suppressants reduced dust levels by up to 75% under controlled conditions.
• Evaluation utilized a systematic approach across various mixtures and conditions, measuring dust suppression efficiency.
• Findings highlight the need for further testing of suppressants across different environmental settings for broader application.
