This paper addressed the issues of poor water quality,high hardness,excessive impurities,and elevated levels of acid,base,and salt ions in underground coal mines.Focusing on the damage caused by these water quality problems to hydraulic system equipment,it introduced the structure,process,principles,functions,and key technologies of an intelligent water treatment and purification station for coal mines.The primary functions of this equipment were highlighted,encompassing three-stage filtration,automatic cleaning,automatic monitoring,automatic dosing,and remote monitoring.The key technologies involved in these functions are elaborated upon:three-stage filtration utilizes three types of filter media to produce water with varying degrees of filtration precision,automatic cleaning achieves maintenance-free operation through the integration of three cleaning mechanisms,automatic dosing implements automatic drug injection via a hydraulic dosing device,remote monitoring enables online monitoring through a network of sensors,control hosts,and Ethernet connections.Upon deployment in an underground mine in Shendong,this equipment has demonstrated remarkable efficacy in removing acid,base,and salt ions from mine water.The pre-and post-treatment deionization results were significant.The system employs both differential pressure and time-based modes for intelligent,three-stage cleaning,facilitating practical applications in the promotion of automation technologies and remote monitoring for coal mine equipment.Real-time,automated data transmission from underground to surface monitoring systems has been achieved.While meeting the mine′s requirements for water quality and flow rate,this equipment realizes automatic monitoring and unattended operation,thereby reducing labor intensity,enhancing the management level and production efficiency of underground coal mine equipment.It merits further promotion and application.
