Abstract In deep coal seams where intact coal interbeds with tectonic coal, the advancement of excavation working faces towards tectonic coal zones, under in-situ stress and gas pressure, is highly susceptible to induced coal and gas outbursts. To investigate the influence of distance on outburst mechanisms during the approach of excavation faces to tectonic coal zones, this study focuses on an outburst-prone coal seam from a mine in Henan. A “tectonic coal mass” experimental model was established to simulate tectonic coal zones embedded within intact coal. Using a self-developed true triaxial coal and gas outburst simulation test system, outburst simulation experiments were conducted at varying approaching distances (L) ranging from 0 to 35 mm between the excavation face and the tectonic coal zone. Throughout the experiments, acoustic emission (AE) technology and temperature sensors were employed to monitor the entire outburst process. New parameters, including the cumulative energy growth rate at each stage and the primary and secondary peaks of AE energy, were defined. Based on the relationship between the primary and secondary AE energy peaks, precursor coefficients for low, medium, and high outburst risks were proposed. The study analyzed AE evolution patterns and temperature characteristics within the tectonic coal zone at different approaching distances. The research findings indicate: (1) A critical approaching distance exists when the excavation face approaches tectonic coal zones. Under consistent in-situ stress conditions, the unit outburst intensity demonstrates a quadratic relationship with the approaching distance, initially increasing and then decreasing. A critical value of unit outburst intensity is observed at an approaching distance of 20 mm. (2) During the outburst incubation stage, the cumulative energy growth rates (K?, K?, K?) exhibit a distinct two-phase trend in relation to the approaching distance: a positive correlation between 10–20 mm and a negative correlation between 20–35 mm. The energy release intensity (K?/K?) during the late triggering phase is 7.17–15.59 times greater than that during the early phase (K?/K?). The approaching distance and AE energy release initially increase before subsequently decreasing. (3) The temperature increment during outbursts in the tectonic coal zone first rises and then declines as the approaching distance increases. In the proximal zone, the temperature increase is minimal and primarily influenced by in-situ stress. In the intermediate zone, accelerated fracture propagation and continuous gas pressure loading lead to a significant temperature rise. In the distal zone, the temperature increase diminishes due to the predominant effect of gas desorption endothermic behavior.

Key words： mining engineering coal and gas outburst excavation working face approaching distance tectonic coal area unit prominent intensity acoustic emission energy temperature evolution
