摘要: Abstract This study proposes a new experimental method of monitoring the transmission range coal seam water injection on basis acoustic emission array technology. Through theoretical analysis and verification, data characteristic signs that can confirm to path were found. In accordance with these data, contour was enveloped. Subsequently, transmission’s calculated distance, fracture space parameters which reconstructed by computed tomography (CT) scanning, used modify control points contour. Results compared slices feasibility correctness proposed Furthermore, threshold wave parameter change when touches determined in monitored effective path.
