Mining Engineering: The "Lifeline" of Safe Production
Release date:
Mar 11,2025
In mining scenarios such as coal mines and metal mines, grouting pumps are critical equipment for preventing accidents like roof collapses and gas outbursts. By injecting high-strength slurry into mined-out areas, an artificial false roof can be created to prevent the top strata from caving in. Additionally, in gas drainage roadways, grouting pumps help fill fractures in rock layers, significantly reducing the risk of gas leakage.
Take a coal mine in Shanxi as an example: it uses the 2ZBQS-30/5 pneumatic dual-fluid grouting pump to inject Marisane chemical grout into fractured roof strata during the longwall mining process. This reinforcement improves roof integrity by 80% and boosts support frame shifting efficiency by 40%, while simultaneously keeping gas concentrations within safe limits. Meanwhile, in deep-metal mines, the grouting pump is integrated with an intelligent grouting system that continuously monitors rock stress changes, automatically adjusting grouting pressure and flow rate to achieve optimal "support" of the surrounding rock mass.
