This device is specifically developed for drilling operations in underground coal mines, integrating intelligent dust removal, gas control, and emergency safety features. Through the synergistic action of a negative pressure generator and a dust collector, it captures drilling dust and gases, preventing pollutant accumulation and ensuring worker health and construction efficiency. The system automatically directs released gas into extraction pipelines and regulates gas concentration in real time. It is equipped with high-precision gas sensors and a dual safety protection mechanism: the primary threshold triggers audible and visual alarms and cuts off the drilling rig’s power supply; the secondary threshold activates an electric ball valve to seal the borehole and guide gas into the pipeline. This mechanism can eliminate the risk of gas outbursts and significantly enhance underground operational safety.
