Pipe Piles and Key Stratum Modeling for Grouting Reinforcement of Mine Floors under Mining Disturbance and Microseismic Monitoring Evaluation

Owing to the increasing applications and popularity of grouting reinforcement technology for water control in mine floors, its effect is becoming increasingly concerning. However, lack an effective evaluation method floor composite limestone aquifers under different treatment modes can lead blindness randomness engineering. Thus, based on engineering practices, we analyzed prevention inrush from working face transformation modes. Moreover, established a sub-model “pipe pile” that was reinforced by cross-layer drilling “water-resistant key stratum” regional grouting, while also simulated concrete function structural models formed two Different microseismic monitoring arrays were used monitor evaluate floor. The results revealed noticeable differences characteristics during mining process This provides basis evaluating effect.
