唐口矿井为提高灌浆防火的效果,对井下移动式制浆装置、控制系统、输送设备及管路等的选型和长距离注浆工艺进行研究。在采煤工作面进行了成套装备的注浆防灭火试验和应用。应用表明:该系统可自动添加制浆组分,浆液浓度稳定;具有操作简单、使用与维护方便等特点,提高了矿井防治采煤工作面自然发火的能力。
In order to improve the effect of grouting and fire prevention, Tangkou Mine researched the selection and long distance grouting of mobile pulping equipment, control system, conveying equipment, pipeline and so on. In the coal mining face of a complete set of equipment grouting anti-fire test and application. The application shows that the system can automatically add pulping components, the slurry concentration is stable, and has the advantages of simple operation, convenient use and maintenance, and the like, thereby improving the ability of the mine to prevent and control coal spontaneous combustion.
