AI Technical Summary
Existing technologies make it difficult to accurately determine the optimal time for gas extraction, resulting in poor gas extraction effectiveness, safety hazards, and resource waste.
By dividing the coal mine's fully mechanized mining area into multiple extraction units, data on gas concentration, extraction negative pressure, and flow rate of each unit are obtained, evolution curves are plotted, and the optimal extraction time is dynamically determined by combining weighting coefficients and confidence level verification.
It enables precise control of gas extraction, reduces safety accidents, improves resource utilization, optimizes the ventilation system, extends equipment life, and avoids unnecessary energy consumption and resource waste.
